STOP WATCHING SWIMMING VIDEOS! Float then swim — Transcript
Full transcript
- 0:00Here are three reasons why adults
- 0:01struggle to swim smoothly while some
- 0:04kids learn this skill much faster.
- 0:06Number one, adults listen to online
- 0:08advice intended for children. Number
- 0:11two, adults think about every move
- 0:13instead of using rhythm and flow. Before
- 0:16I tell you the third, you have to know
- 0:17this. Adults have several advantages
- 0:20over kids. One of them is that they'll
- 0:23understand this video much better than
- 0:25kids. And second is that adults have
- 0:27more context. Just look at Barrett at
- 0:30age 39. Without context, it is
- 0:33impossible to understand what he
- 0:34achieved in one day. In just 24 hours,
- 0:38he improved his stroke efficiency from
- 0:4030% to 50%. Six days later, he wrote a
- 0:44message to us saying, "I have been stuck
- 0:47for years, years at 1:35 per 100 m pace.
- 0:51Didn't matter what I did, stroke,
- 0:53effort, tempo, technique, 1:35.
- 0:55Yesterday was my first swim back in the
- 0:58pool. I hopped in and was too eager to
- 1:01find out, so I did a 100. And
- 1:041:15. A 20-second drop in 100 m. Seems
- 1:08impossible, right? If I were you, I
- 1:09wouldn't believe it either. But I do
- 1:11because I got to know him for 5 days and
- 1:14I filmed and recorded the data. Consider
- 1:17this. Why do strong, disciplined, fit
- 1:20adults get in the pool and feel heavy?
- 1:22How can a 65-year-old woman who's never
- 1:25set foot in a gym glide past them
- 1:27effortlessly in the water? Here's a
- 1:29clue. In a study of 98 men, after a
- 1:32normal breath out, only seven could
- 1:34float. After a full breath, every single
- 1:37one of them could float with their lungs
- 1:39full of air. After teaching thousands of
- 1:41adults and kids from 48 countries, I can
- 1:44tell you this. Nobody talks about what
- 1:46makes adult swimming so difficult. As
- 1:49swimmers, the three of us never
- 1:50qualified for the Olympics. But as
- 1:52coaches, we've helped every level of
- 1:55swimmer understand aquatic movement much
- 1:58deeper.
- 1:59From Olympians to beginners, we have
- 2:01worked with the full spectrum. And what
- 2:03I'm about to show you in the next 50
- 2:06minutes will change how you swim
- 2:07forever. Including a study where MRI
- 2:10scans caught elite swimmers doing
- 2:12something inside their own body that
- 2:14nobody could see from the outside. I'll
- 2:16teach you how to do it, too. As adults,
- 2:19these should be our main two goals:
- 2:21float like a butterfly and swim like a
- 2:23fish in that order. So, one for the
- 2:26other and you'll be eventually confused
- 2:29and stagnant.
- 2:35Here's what I've learned. Children float
- 2:37easily if they're taught correctly. Many
- 2:39elderly people float naturally if they
- 2:41don't panic. Women float more easily
- 2:44than men.
- 2:45And elite athletes are some of the worst
- 2:47floaters in the pool. I was one of them
- 2:49until I received this letter and I
- 2:51finally understood the concept of the
- 2:53two centers. Three years ago, I wrote a
- 2:56letter to my 7-year-old self with
- 2:58everything I wish I knew about swimming
- 2:59fast and how to become the fastest
- 3:01swimmer in the world. That video has
- 3:03over 2 million views across our Spanish
- 3:05and English channels. Last week, I got a
- 3:08letter back. This time written by my
- 3:1046-year-old self. He told me it was time
- 3:13to stop writing to kids. It was time to
- 3:15help the adults and it starts like this.
- 3:18Dear 36-year-old me, this is you from
- 3:202036. You're going to spend the next 10
- 3:23years researching why adults struggle to
- 3:25improve faster. I'll save you time. The
- 3:27problem was never the swimmers. It was
- 3:30what they were told, including some of
- 3:32what you teach right now. Adults are
- 3:34giving too many instructions and what is
- 3:36worse, it is not prioritized by order of
- 3:39importance. Here are five tips that will
- 3:41change how you swim and more
- 3:43importantly, how you teach.
- 3:51David Foster Wallace told this story in
- 3:53his speech This is Water. Let it linger
- 3:55in your mind and it will teach you many
- 3:57things. It goes something like this. Two
- 4:00young fish are swimming along and they
- 4:02pass an older fish going the other way.
- 4:04The older fish nods and says, "Morning,
- 4:06boys. How's the water?" The two young
- 4:08fish keep swimming for a bit and then
- 4:10one of them looks over at the other and
- 4:12goes,
- 4:13"What the hell is water?"
- 4:15David Foster continues, "The point of
- 4:16this story is merely that the most
- 4:18obvious important realities are
- 4:21the ones that are the hardest to see and
- 4:23talk about." For us, this story contains
- 4:26one deeper and another more literal
- 4:29lesson. Young swimmers don't even notice
- 4:31the water. They just glide through.
- 4:33Smart, athletic, disciplined adults get
- 4:35in the pool
- 4:37and they feel like they're swimming
- 4:38through quicksand. The adult swimmers
- 4:39tell themselves, "Swimming is hard. I
- 4:42need to watch more videos, practice
- 4:44harder, get even stronger." And that's
- 4:47not an answer. Listen to what Maria
- 4:49says.
- 4:49>> I feel like swimming is very different
- 4:51than running in the sense that with
- 4:53running, the more you do it,
- 4:55the more you improve. So, you just go
- 4:56out and you do it and do it and do it
- 4:58and with time you'll get better. And I
- 5:01didn't notice the same thing with
- 5:02swimming.
- 5:03>> The real answer is more obvious and
- 5:04invisible, just like the water in the
- 5:06story.
- 5:09Here's what none of the swim coaches
- 5:11have told you. You're a master of moving
- 5:13through the air. You're so good at it
- 5:15that you don't even notice it's there.
- 5:17Cyclists might think about air more than
- 5:19anyone else, but the rest of us move
- 5:21through it as if it doesn't exist.
- 5:23That's why when we change to a dense
- 5:25medium, we struggle. On land, we use our
- 5:27bodies like a spring. We make ourselves
- 5:30heavy against it, absorb energy, release
- 5:34it, and bounce forward. The harder we
- 5:37push, the faster we go. People who feel
- 5:39light on their feet are masters of
- 5:41pushing the ground hard. In the water,
- 5:43the rules flip. You can't push the water
- 5:46the way you push the ground. And
- 5:48resistance doesn't come from a light
- 5:50medium like air. Try a water rower. Pull
- 5:53slowly and the resistance is low. Pull
- 5:56fast and the resistance increases. The
- 5:58harder you try, the more the water
- 6:00pushes back. In swimming, drag doesn't
- 6:03care how hard you pull. It cares about
- 6:05your shape and your speed. Drag forces
- 6:08scale with the square of your velocity.
- 6:11Which means going twice as fast creates
- 6:13four times the resistance and it scales
- 6:16directly with your frontal area. Every
- 6:19extra square centimeter your body
- 6:21presents to the water multiplies that
- 6:23cost. When your legs sink, they don't
- 6:26just add drag. They add drag that gets
- 6:29more expensive the faster you try to go.
- 6:31That's the trap of swimming out of
- 6:33balance. But when your body is
- 6:34horizontal and when your legs sit behind
- 6:37your upper body's silhouette as seen
- 6:39from the front, your frontal area stays
- 6:42small. Speed no longer punishes you the
- 6:44same way. That's not a technique tip.
- 6:47That's physics working for you instead
- 6:49of against you. To find a horizontal
- 6:51body position, you need to understand
- 6:54the two centers, which we will talk
- 6:55about more in the next tip. Have you
- 6:57ever wondered why a track athlete can
- 6:59run almost the same speed when they
- 7:01double the distance, but a swimmer
- 7:03can't? Runners lose almost nothing when
- 7:06they double from 100 to 200 m. Swimmers
- 7:09lose their speed with every extra lap.
- 7:12By 400 m, the fastest swimmer in the
- 7:14world is moving 16% slower than the
- 7:18100-m world record pace.
- 7:20By 1500, 20% slower. But notice
- 7:23something else on the chart. After 400
- 7:25m, the two lines cross. The runner keeps
- 7:28falling. The swimmer levels off.
- 7:31Past 400 m, the physics flip. The
- 7:33swimmer is no longer losing too much
- 7:35ground to the drag. The runner is losing
- 7:38ground to fatigue. That's the tell. At
- 7:40short distances, water punishes you for
- 7:42trying hard, at long distances, water
- 7:44rewards you for staying horizontal
- 7:47because drag rises with the square of
- 7:49velocity, which brings us back to the
- 7:52point. If your goal is to swim fast, you
- 7:54need to get strong and be extremely
- 7:56efficient. If your goal is to swim
- 7:58smoothly, then horizontal body position
- 8:01is the priority. Efficiency comes
- 8:03second. Power comes third. I'll say it
- 8:06one more time so you remember it next
- 8:07time you swim. If you feel heavy and
- 8:10breathless every time you push hard in
- 8:12the water, stop chasing speed and start
- 8:14chasing weightlessness. But if your legs
- 8:17naturally sink, how does someone stay
- 8:19horizontal?
- 8:21Remember what I promised at the start. I
- 8:23said, a study used MRI scans on elite
- 8:27swimmers. When they extended into
- 8:29streamline, something remarkable showed
- 8:31up. Their internal organs had shifted
- 8:34cranially. They weren't lifting their
- 8:36legs, they were not tightening the core,
- 8:38they were rearranging themselves from
- 8:40the inside. You have a center of
- 8:42buoyancy and a center of mass. On
- 8:45average, they're separated by about 2 cm
- 8:48for some people more than others. That's
- 8:51how averages work. Fish don't have this
- 8:53problem. Their two centers sit right on
- 8:55top of each other. That's why they feel
- 8:57weightless. They're not fighting
- 8:58themselves. Imagine a boat where half of
- 9:01it is always sinking while the other
- 9:03half is always floating. It would be
- 9:05very difficult to make it light. That's
- 9:07the adult swimmer. Two centers, one
- 9:09pulling down, the other pulling up.
- 9:11Weightlessness isn't a feeling you
- 9:13chase, it's what happens when your two
- 9:15centers stop fighting each other and
- 9:18start acting like one. One of the most
- 9:20common mistakes is pulling water down at
- 9:22the beginning of the stroke. This
- 9:24separates the two centers even more and
- 9:26immediately brings the hips down. That's
- 9:29why the 30-year-old tries harder, pulls
- 9:32harder, and only makes things worse. His
- 9:34strength is working against him, and
- 9:36then it gets Kate. If his hips drop, he
- 9:39lifts his head too far to breathe. The
- 9:41body sinks more. He pulls harder, uses
- 9:44more energy, burns more oxygen, produces
- 9:47more CO2, anxiety creeps in. By the
- 9:50third lap, Claire is using 20% of her
- 9:53effort to get from one side of the pool
- 9:55to the other. And the fit adult is at
- 9:5790% and getting slower with every
- 9:59length. Maybe he doesn't start with all
- 10:01these problems, but one or two will show
- 10:04up the moment his body gets tired. When
- 10:07swimmers move their internal organs up
- 10:09toward their lungs, both centers draw
- 10:11closer together. That means that the
- 10:13legs pull down with less effort. Each
- 10:16arm stroke can go further. After reading
- 10:18this study, I tried it and it worked
- 10:20like nothing else I have ever done
- 10:23before. Here's the part that matters for
- 10:25you. Most of them weren't doing it on
- 10:27purpose. They had trained it without
- 10:29knowing they were training it. Nobody
- 10:30had told them what they were doing. I've
- 10:32been teaching people in our camps and in
- 10:34our app how to do it on purpose. It
- 10:36works. Today, I'm going to teach you so
- 10:39you can teach everyone. But first, you
- 10:41need to understand why it worked. And to
- 10:43understand that, we need to talk about
- 10:45why your legs sink in the first place.
- 10:48It's not effort. It's not technique.
- 10:50Many people say engage the core. That is
- 10:52not it. In fact, it can make things
- 10:55worse. Here's what happens when you
- 10:57engage the core. Your legs sink faster.
- 11:00After teaching hundreds of people how to
- 11:02float better, here are three things I've
- 11:05learned. Children and the elderly are
- 11:07the best horizontal floaters. Women
- 11:09float better than men. Elite athletes
- 11:12and even elite swimmers are some of the
- 11:14worst natural floaters. So, why are
- 11:17elite swimmers moving better in the
- 11:19water than children and the elderly?
- 11:21Take a muscular 25-year-old triathlete
- 11:23and a 65-year-old Claire. Ask both of
- 11:26them to float on their backs. Claire
- 11:27wins. Not because her technique is
- 11:29better, but because her body is
- 11:31literally more buoyant than his. Here
- 11:34are two centers again. This is your
- 11:36center of mass and this is your center
- 11:38of buoyancy. In the water, you stay
- 11:40horizontal if those two points are
- 11:42perfectly aligned. If they're separate,
- 11:45the upper body floats and the lower body
- 11:47sinks. But why the separation? Your body
- 11:49is made out of different tissues: fat,
- 11:52muscle, bone, blood, air. Each one has a
- 11:54different density. And density decides
- 11:57whether you sink or you float.
- 11:59Archimedes figured this out a long time
- 12:01ago. If you're less dense than the water
- 12:03around you, you float. If you're denser,
- 12:06you sink. Here's the part that nobody
- 12:08tells you. Fat is the only solid tissue
- 12:11in your body that is less dense than
- 12:13water. Fat floats at 0.9. Muscle sinks
- 12:17at 1.06.
- 12:19Bone sinks the hardest, between 1.3 and
- 12:222.0. So, if you've been hitting the gym,
- 12:25building muscle, cutting body fat,
- 12:27getting lean and strong for your
- 12:30triathlon or your CrossFit competition,
- 12:32congratulations. You just made yourself
- 12:35a worse floater. Every kilogram of
- 12:37muscle in your lower body pulls your
- 12:38hips down. Every percentage point of
- 12:41body fat you lost is making your body
- 12:43denser. Your legs will pull you down
- 12:45harder. Claire has more body fat, less
- 12:48muscle, and lighter bones. She doesn't
- 12:50try to float. Her body does it for her.
- 12:53In fact, she has trouble swimming
- 12:54underwater because she floats too much.
- 12:57Some things that make you better on land
- 12:59make you worse in the water. And before
- 13:01anyone blames their heritage, one more
- 13:04thing. There's a long-standing myth that
- 13:06black communities can't float because of
- 13:08heavier bones. Bone density does vary
- 13:10between populations on average, but bone
- 13:13is only about 15% of body mass. And what
- 13:16actually decides floating is the air
- 13:18inside your lungs. A 2025 study from the
- 13:21University of Portsmouth tested this
- 13:23directly. They recruited people from
- 13:25African, Caribbean, and Asian
- 13:27communities scanned their bone density
- 13:29with DEXA scans and asked them to float
- 13:31for 2 minutes after instruction. 89 out
- 13:34of 96 succeeded. The conclusion? Bone
- 13:37density showed no correlation with
- 13:39floating ability. Body fat and breathing
- 13:41technique did. So, how do the fastest
- 13:43swimmers in the world stay horizontal if
- 13:46they are very muscular and their bodies
- 13:48want to sink? They do two things. One,
- 13:51they keep air in their lungs, never
- 13:54fully exhaling, more on that shortly,
- 13:56and two, they shift their weight forward
- 13:59towards their head. Watch any elite
- 14:01swimmer. Every coach wants to see their
- 14:03shoulders close to their ears.
- 14:05Streamline, dolphin kick, freestyle,
- 14:07backstroke, breaststroke, and butterfly,
- 14:09all of them swim with their shoulders
- 14:12touching their ears. Yes, it reduces
- 14:14drag, but what most people don't know is
- 14:16that it also pulls the center of mass
- 14:19closer to the center of buoyancy. In
- 14:21freestyle, smooth swimmers always keep
- 14:23at least one arm in front of the
- 14:25headline. Same reason. Mass moves
- 14:27forward, but by far the most powerful
- 14:29and hidden version of this is moving
- 14:31your guts cranially while keeping air in
- 14:34your lungs. A 2020 study by Yoshida and
- 14:37colleagues, published in Scientific
- 14:38Reports, used MRI to scan elite swimmers
- 14:42in streamline. When the swimmers drew
- 14:43their abdomen in, their internal organs
- 14:46physically shifted upward towards the
- 14:48chest. That redistribution moved their
- 14:51center of mass closer to the center of
- 14:52buoyancy, less leg sinking torque,
- 14:55longer glides, a mechanism completely
- 14:57invisible outside of the body. Even most
- 15:00elite swimmers don't even know they're
- 15:01doing it. Here's how to do it on
- 15:03purpose. It might take practice. Lay on
- 15:05the floor face down or face up. Take a
- 15:08deep breath in. Feel the lower two ribs
- 15:10expand. Tuck your stomach in without
- 15:13letting air out. Think of pulling your
- 15:15belly button towards your spine. Now,
- 15:17the part that most people skip, keep
- 15:19your pelvic floor tight at the same
- 15:22time. You don't want to push your guts
- 15:24the other way because that will cause an
- 15:26accident in your underwear. If you don't
- 15:28know what your pelvic floor is, picture
- 15:31this. You're at a mall, your stomach
- 15:33hurts, you run to the bathroom, there's
- 15:35a sign on the door, "Temporarily
- 15:37closed." You have to drive home. The
- 15:39thing you're squeezing for the entire
- 15:42drive, that's your pelvic floor. Lungs
- 15:44full, belly button in, pelvic floor
- 15:46tight. That's exactly how you should be
- 15:49swimming. Try it on land first, then
- 15:51take it to the water. You don't need a
- 15:53lot of tension, but to find the right
- 15:55amount, you'll need to exaggerate first.
- 15:58Same logic as any other muscle.
- 16:00You lift heavy, you get stronger, and
- 16:02after a few days, everything you carry
- 16:04feels lighter. Do reps of this. You'll
- 16:07get stronger in the position. Like
- 16:09everything we do, at first it's
- 16:11intentional, and with time becomes
- 16:13natural. This advice is different than
- 16:15what you've heard. Most YouTube videos
- 16:17focus on what Olympians do at race
- 16:19speed. They analyze the catch, the pull,
- 16:21the kick, the timing, and the rotation.
- 16:23All of that matters at race speed over
- 16:25short distances, but here's what they
- 16:27don't tell you. Young swimmers spend
- 16:29years building what the best coaches
- 16:31call dynamic buoyancy. They use speed,
- 16:34kick, head position, and arm strength to
- 16:37generate lift that holds their body
- 16:38horizontal. They don't float. They pull
- 16:41through the water. The faster they go,
- 16:42the easier it is to stay up because the
- 16:45kick is fast enough to keep their legs
- 16:47from sinking. The result is that many
- 16:49kids can't swim smoothly. They only know
- 16:52how to swim hard. They are taught to
- 16:54swim fast and long using a lot of
- 16:56effort. Only a few of them, the
- 16:58naturally gifted, manage to swim
- 17:00smoothly with that good feel for the
- 17:02water despite not thanks to their
- 17:05mediocre coaching. Many of your adult
- 17:07swimmers are not looking for that.
- 17:09They're not swimming 55 seconds per 100
- 17:12m.
- 17:13They're swimming at 1:45 or 3 minutes.
- 17:16At those speeds, dynamic lift barely
- 17:19exists. They can't kick fast enough to
- 17:21compensate. And, frankly, they shouldn't
- 17:23even try if they want to swim long
- 17:25distances smoothly. Nobody taught them
- 17:27how to float first because everyone
- 17:30skipped straight to the teaching how to
- 17:31move their arms. The advice designed for
- 17:34young swimmers can hurt adult swimmers.
- 17:36What works at race pace fails at
- 17:38learning pace. If you copy what elite
- 17:41swimmers do without understanding why
- 17:43they do it, you will just burn more
- 17:45energy fighting the water. So, what does
- 17:47work at slower speed? Understanding your
- 17:50body's buoyancy. Practicing horizontal
- 17:52glide while shifting the weight forward.
- 17:55So, if your legs sink and the kick
- 17:57doesn't help, it's time to move your
- 17:59guts and your shoulders forward.
- 18:02Achieving a horizontal body line is a
- 18:04great achievement, but what happens when
- 18:06the whole body sinks? We're not fish. We
- 18:09have to get our face out of the water to
- 18:12breathe. And if we're too low in the
- 18:13water, we reach for air and disrupt the
- 18:16very horizontality we just worked so
- 18:19hard to build.
- 18:24In swimming, your lungs aren't for
- 18:25breathing. They're your inner life
- 18:27jacket. Picture your lungs as an
- 18:29accordion. By keeping at least 50% of
- 18:32the air inside, you keep your body's
- 18:34density under the 1.0 threshold. Exhale
- 18:37everything, even for a second, and you
- 18:39sink. Remember the study from the start
- 18:42of the video? With full lungs, 100% of
- 18:45them could float. A full breath of air
- 18:47displaces several liters of water.
- 18:49That's several kilograms of lift just
- 18:52from breathing in. We're carrying a
- 18:54built-in life jacket. Most adults have
- 18:56no idea how to use it. Your lungs are in
- 18:59your chest. Your legs are mostly muscle
- 19:01and bone. These are the densest part of
- 19:03your body with no air inside of them at
- 19:05all. Your buoyancy is all in one place.
- 19:08Your weight is in another.
- 19:10And that's why your two centers don't
- 19:12line up. They're offset by about 2 cm
- 19:14when your hands are overhead. Sounds
- 19:16like not a lot, but it creates
- 19:18rotational force like a seesaw where one
- 19:21kid is always heavier than the other.
- 19:23Your chest rises, your legs fall. Your
- 19:26legs aren't sinking because your kick
- 19:28wrong, but you can keep them high
- 19:30without kicking at all. They're sinking
- 19:32because of where your air is. This is
- 19:34also why women float better than men,
- 19:36not just body fat. It's where the fat
- 19:39sits. Women carry more mass around the
- 19:41hips and thighs, right where the body is
- 19:43the densest. That moves their center of
- 19:45gravity closer to the center of
- 19:47buoyancy. One study of collegiate
- 19:49swimmers found men had 0.79 cm offset.
- 19:53Women only 0.16. That's why most men
- 19:56feel a huge difference with a pull buoy
- 19:58between their legs. The pull buoy is
- 19:59doing what the female body composition
- 20:01does for free. Older swimmers lose
- 20:03muscle and bone density with age. Both
- 20:06of those tissues are denser than water.
- 20:08Losing them actually helps you float.
- 20:10The 65-year-old woman passing the
- 20:12triathlon isn't floating despite her
- 20:14age. She's floating partly because of
- 20:17it. Floating isn't her problem. She
- 20:19might need to hit the gym more often,
- 20:21but floating is easy.
- 20:23Most adults breathe in the water the way
- 20:25they breathe on land. That's a mistake.
- 20:28On land, you breathe for oxygen. In the
- 20:30water, you breathe for buoyancy. So, how
- 20:33do we actually use this inner flotation
- 20:35device? You need effort to inhale and
- 20:37relaxation to exhale. Left alone, your
- 20:40lungs contract. To inflate them, your
- 20:43ribs and diaphragm have to pull them
- 20:45open. The intercostal muscles expand the
- 20:47ribcage. The diaphragm contracts and
- 20:50pulls down, expanding the chest cavity
- 20:52and pulling air in. That's why you need
- 20:54energy to breathe in, but relaxation to
- 20:57breathe out. Here's why this matters in
- 20:59the water. The exhale activates your
- 21:01parasympathetic nervous system. It's the
- 21:04chemical signal for calm. The inhale is
- 21:06mild activation, a small dose of
- 21:09alertness. This is why anxious swimmers
- 21:11almost always feel like they need more
- 21:13air. This is why many swim teachers tell
- 21:16them to exhale slowly so they feel
- 21:18calmer. That works in yoga, but in
- 21:20swimming those instructions make you
- 21:22sink. You might feel calmer, but you
- 21:24won't swim smoothly anytime soon. To
- 21:27inflate your inner life jacket in the
- 21:28water,
- 21:29you have to use these muscles and like
- 21:32any muscles,
- 21:33they get weaker when you don't use them.
- 21:35They atrophy. Most adults don't move
- 21:37their rib cages enough. I remember when
- 21:39I tweaked one intercostal muscle. I was
- 21:42too stiff from sitting too much and
- 21:44didn't warm up the rib cage before
- 21:45exercising.
- 21:47Here's one way to start training these
- 21:48muscles. First, stretch them slowly.
- 21:51There are many ways to stretch them.
- 21:52Here are a few.
- 22:01Then, lie on the floor. Put two heavy
- 22:03books on your body.
- 22:05One on your stomach, and one on your
- 22:07chest. The weight simulates the pressure
- 22:10you feel underwater. If you're more
- 22:12advanced, swap the books for small
- 22:13weights. Then, train it like any other
- 22:15muscle. Three Rs: rounds, repetitions,
- 22:18and rest. A starting point: three rounds
- 22:20of five reps. First, lift the book on
- 22:23your belly five times.
- 22:26Then, the book on your chest five times.
- 22:29Then, both at the same time five times.
- 22:31Five reps of each variation is one
- 22:34round. Warm up with no weights for round
- 22:36zero. Each rep should last 5 seconds in,
- 22:393 seconds hold, and 5 seconds out. Young
- 22:42swimmers probably don't need this. Most
- 22:44adult swimmers absolutely do.
- 22:46Their breathing muscles have weakened
- 22:48with age.
- 22:49Even yogis can benefit from this
- 22:51exercise. In swimming, you don't breathe
- 22:54when you want. You breathe when you
- 22:56can't. And to breathe when you should
- 22:58takes trial, error, and smart practice.
- 23:00For more instruction on when and how
- 23:02often to breathe, refer to your
- 23:04breathing course inside the app. Some
- 23:06people sink more than others. Everyone
- 23:08can learn to use their inner life
- 23:09jacket, but your audience isn't going to
- 23:11spend the full hour in the pool doing
- 23:14breathing drills. Contrary to what
- 23:15people think, that level of breathwork
- 23:18is reserved for advanced swimmers, not
- 23:20the average adult. 15 minutes of
- 23:22learning to keep air inside and float
- 23:24horizontally is enough. Then, here's
- 23:26what they should focus on next.
- 23:38There are two ways to teach the
- 23:40mechanics of swimming without the
- 23:41problem of breathing getting in the way.
- 23:43Most adults won't try either of them.
- 23:45Their ego gets in the way. They think it
- 23:47feels like cheating, and they don't want
- 23:49to look like a loser in the pool. That's
- 23:51their ego talking. Here's what the
- 23:53science says. Stanford researchers set
- 23:56out to find what people who multitask
- 23:58all the time are better at. They found
- 24:00nothing. Heavy multitaskers were worse
- 24:03at filtering irrelevant information,
- 24:05worse at managing memory, worse at
- 24:08switching between tasks than people who
- 24:10rarely multitask. The researchers were
- 24:12shocked. The more you multitask, the
- 24:14worse you get at all of it. A separate
- 24:172014 study by Loh and Kanai used MRI to
- 24:21scan the brains of heavy media
- 24:22multitaskers. Their anterior cingulate
- 24:24cortex, the region responsible for
- 24:27directing attention, was physically
- 24:29smaller than the controls. The brain
- 24:31doesn't adapt to multitasking. It
- 24:33atrophies, and the part that atrophies
- 24:35is exactly the part you need to learn to
- 24:37swim better. The anterior cingulate
- 24:38cortex is your brain's air traffic
- 24:41control. It tells the noise to wait
- 24:43while you focus on one thing. If you
- 24:45spend 10 years answering emails while
- 24:47watching TV, texting, and watching
- 24:49short-form content, you've spent 10
- 24:51years training that controller to give
- 24:53up. The water is one of the most chaotic
- 24:56environments. Sensory inputs are
- 24:58overloaded. If you don't know how to
- 25:00stay focused, information becomes
- 25:03overwhelming and improvement stagnates.
- 25:06The human mind lacks the architecture to
- 25:08do two cognitive or physical tasks at
- 25:11once. We are serial processors, not
- 25:13parallel. Our brains love focused
- 25:16attentions. Our phones love
- 25:17distractions. Clearly, we're feeding the
- 25:19wrong one. And when we try to swim
- 25:21better, it shows. And that's why in the
- 25:23water sometimes we close our eyes. Not
- 25:26as a gimmick, as a way of giving an out
- 25:29of shape attention system one less thing
- 25:31to manage. You know you can't swim with
- 25:34your eyes closed all the time because
- 25:36you bump into things or people. So, grab
- 25:38the edge of the pool and simulate the
- 25:40pool with your eyes closed.
- 25:43The problem isn't that adults think too
- 25:45much, is that they're thinking about too
- 25:47many things at once. To find flow and
- 25:49rhythm in the water, you need to use
- 25:51your cerebellum. The cerebellum sits at
- 25:53the base of your skull. It doesn't
- 25:55initiate the movement, it refines it.
- 25:57Most adults aren't swimming from the
- 25:59cerebellum, they're swimming from the
- 26:00prefrontal cortex, the front of the
- 26:03brain that handles conscious thought. Am
- 26:05I doing this right? Are my hips too low?
- 26:08Why am I out of breath already? What if
- 26:10everyone is looking at me? The
- 26:11prefrontal cortex is powerful but
- 26:13expensive. And it can only hold a few
- 26:15things at once. It's not smooth. The
- 26:18moment self-consciousness shows up, it
- 26:20spends its bandwidth on self-conscious
- 26:23thoughts instead of flow. Research on
- 26:26athletes choking under pressure shows
- 26:28that the more attention you pay to your
- 26:29own technique, step-by-step, the more
- 26:32the movement falls apart. The work of
- 26:34learning to swim smoothly is moving the
- 26:36job from the prefrontal cortex down to
- 26:39the cerebellum. You can't ask the
- 26:40cerebellum to take over. It only learns
- 26:43the job through repetition. Give the
- 26:45prefrontal cortex one thing to focus on,
- 26:48strip away every other source of noise,
- 26:50and repeat the correction until the
- 26:52cerebellum builds its own map of it.
- 26:55Then the cerebellum takes over and the
- 26:56prefrontal cortex goes quiet. At this
- 26:59point, repetition becomes boring. Only
- 27:01then may you introduce variability or
- 27:04higher levels of skill development. I'll
- 27:06show you what that looks like. That's
- 27:07why we close our eyes even for a second.
- 27:10But before we can close our eyes and
- 27:12focus on the right model, we have to
- 27:14remove the noise. This is the fastest
- 27:16way to rewire your brain to swim better.
- 27:19Put on a pull buoy, snorkel, nose clips,
- 27:21fins, and even paddles. The pull buoy
- 27:23floats because it traps air in tiny
- 27:25holes. It pulls the legs up, aligns the
- 27:28center of mass with the center of
- 27:29buoyancy, and removes legs sinking from
- 27:31the equation. The snorkel removes the
- 27:33movement of moving your head to breathe
- 27:35from the equation. Nose clip. Most
- 27:37adults panic when water goes up their
- 27:39nose with the snorkel. The clip removes
- 27:42that variable, too. Now, we've
- 27:44eliminated breathing movement, leg
- 27:46position, and balance. But there's still
- 27:48two arms moving at the same time, and
- 27:50the sensations from both are competing
- 27:52for our attention. So, we go further.
- 27:54One arm at a time. Paddles to exaggerate
- 27:57the sensation, both right and wrong, so
- 28:00the brain can tell the difference. And
- 28:01finally, we close our eyes.
- 28:04The eyes are gathering tons of
- 28:05irrelevant information.
- 28:07Tiled patterns, other swimmers, lane
- 28:09lines, your own bubbles. Closing them
- 28:11isn't about focus there. It's about
- 28:13removing the last and largest source of
- 28:15noise, so the brain can lock onto the
- 28:17one thing we're trying to teach it. This
- 28:20works only after many repetitions. In my
- 28:22experience, 50 to 400 arm circles per
- 28:25correction. You can close your eyes just
- 28:27for 2 seconds while you do one or two
- 28:29strokes. Then reopen them again to avoid
- 28:32collisions. Swimming with a pull buoy,
- 28:33snorkel, and fins is easier than
- 28:36swimming without them. That's why people
- 28:37say it feels like cheating. Here's the
- 28:40Skills and Talents philosophy. There's
- 28:41nothing you can do in training that
- 28:43counts as cheating if it helps you
- 28:45improve. You're not competing with
- 28:47anyone in training unless the training
- 28:49calls for it. What you're doing has a
- 28:51name, isolating variables. The water has
- 28:54too many things happening at once. We
- 28:56strip them away one by one until only
- 28:58the point of focus remains. That's a
- 29:00much faster route to rewire old moving
- 29:02pattern than just accumulating meters.
- 29:05You can cheat in a race because there
- 29:07are rules, but you can't cheat in
- 29:08training because there shouldn't be any
- 29:11rules against improving. Now the hard
- 29:13part. We remove the noise, but what are
- 29:15we actually focusing on when we close
- 29:17our eyes? This is where most adult
- 29:19swimmers go wrong. When we close our
- 29:21eyes and picture the perfect stroke, we
- 29:24imagine an Olympian. Don't. We don't
- 29:26have Olympic shoulder skills. Picturing
- 29:28what we can't physically do isn't a good
- 29:31mental model. It's a fantasy that our
- 29:33body will spend our whole life trying
- 29:35and failing to do. Here's a better way.
- 29:38Use the shoulder skills you have. Build
- 29:40the model from there. Most swim videos
- 29:42teach one ideal stroke and try to make
- 29:45everybody fit the mold. That causes
- 29:47injuries. Lift your elbow high, early
- 29:50vertical forearm, reach further, rotate
- 29:52more, pull harder, don't cross, if you
- 29:55can, try harder. That's not helping any
- 29:58real humans. That's only working for an
- 30:00imaginary swimmer with limitless
- 30:02shoulder mobility and strength. There
- 30:03are movements your brain cannot instruct
- 30:05your shoulders to do because there are
- 30:07physical and neurological limitations.
- 30:10Your brain can tell your legs to squat a
- 30:12thousand pounds. Your legs won't do it.
- 30:14You start with weights that you can
- 30:16manage with your current skills and you
- 30:18build from there. Same with the
- 30:20shoulders. Here's the SMT shoulder skill
- 30:22ladder, level one to 10. The shoulder
- 30:25can't stretch overhead at all. Imitating
- 30:27the ideal stroke causes compensations.
- 30:29Arched back, lifted hands, bent elbow,
- 30:32energy wasted forcing the arms straight.
- 30:34Mental model, point the shoulder down on
- 30:37each stroke. Don't reach overhead. Reach
- 30:39forward, down, and wider.
- 30:42Level 11 to 20. The shoulder lifts
- 30:45overhead but can't internally rotate.
- 30:47Pain or mobility limitation. Imitating
- 30:49the ideal stroke causes crossover at the
- 30:52midline, over-rotation, or pulling water
- 30:54straight down. Better mental model,
- 30:56start the catch slowly. Slow enough that
- 30:59you feel the water before you pull it.
- 31:01Start a little wider than normal to
- 31:03avoid discomfort.
- 31:07Level 21 to 30. The shoulder has the
- 31:09range but the catch collapses early.
- 31:12Better mental model,
- 31:13the hand should accelerate through the
- 31:15pull. Here's the velocity of the pull of
- 31:17an efficient swimmer versus one that
- 31:20slows down mid-pull.
- 31:22Level 31 to 40. The shoulder can hit
- 31:25early vertical forearm on land but loses
- 31:28it in the water. The neural connection
- 31:30is missing. A better mental model is
- 31:32isolate one arm with paddles. Feel the
- 31:35EVF position before you try to swim with
- 31:38it.
- 31:40Level 41 to 50. The shoulder can hold
- 31:43EVF but can't produce force from it. A
- 31:46better model, paddles to load the
- 31:48position and build strength. Use the
- 31:50side of your body, the lats, and the
- 31:52rotation to pull.
- 31:55Level 51 to 60. The shoulder can produce
- 31:58force but the force goes sideways
- 32:00instead of pushing the body forward. A
- 32:02better mental model, pull and push
- 32:04towards the pinky toe.
- 32:08Level 61 to 70. The shoulder is
- 32:10propulsive but only in one stroke. A
- 32:13better mental model, get more distance
- 32:15per stroke and then increase the tempo.
- 32:18Practice perfect technique and stop when
- 32:20it starts to fade. To assess your
- 32:22shoulder skill level,
- 32:24use the tests inside the SNT app.
- 32:30Here's what nobody tells adult swimmers.
- 32:33Shoulder mobility is not fixed. It's not
- 32:35gone. It's not your age. A 60-year-old
- 32:38who starts swimming at 50 and moves
- 32:41their shoulders every day can swim with
- 32:44more range than a 30-year-old who sits
- 32:46at a desk all day. If you try to swim
- 32:48with range you don't have, you'll
- 32:50compensate. You'll lift your head,
- 32:52you'll overreach, you'll drop your hips,
- 32:55and you'll get hurt. Step one, assess.
- 32:57Step two, adapt. Step three, train.
- 33:02The Ken came to a swim camp when he was
- 33:0565 years old. He used to do 14 strokes
- 33:08per lap. After the camp, he did 10.
- 33:11That's possible when you clear out the
- 33:12noise and visualize your perfect stroke.
- 33:16If your shoulders can do what a YouTube
- 33:17video tells you to do, your shoulders
- 33:20aren't wrong. The video is wrong for
- 33:22you. Stop watching ideal technique
- 33:24videos. Stop picturing Olympians when
- 33:26your eyes are closed. Use the shoulders
- 33:28you have. Build a mental model that fits
- 33:31your level, then slowly train toward the
- 33:33next one. If you want to feel the
- 33:35difference right now, swim two or three
- 33:37strokes with your eyes closed. 90% of
- 33:39swimming skills live inside the five
- 33:42pillars. Breathing control, balance,
- 33:43core strength, and arm power. And the
- 33:47hardest one of all. We've covered four.
- 33:49Before we teach the last one, we have to
- 33:52go back. The two young fish don't know
- 33:54what the water is. They don't notice it
- 33:56because it's everything they've ever
- 33:58known. I imagine the story continues
- 34:00like this. The two young fish keep
- 34:02swimming, and they meet a frog. The frog
- 34:04tells them he used to know how to swim
- 34:06better when he was very young, but his
- 34:08body is different now, and he wants
- 34:10swimming lessons. The young fish look at
- 34:12each other and say, "What the hell is
- 34:15swimming?" They sense something strange
- 34:17is happening. So, they go find the old
- 34:19fish. The old fish seems even more
- 34:21confused than they are because that's
- 34:23not the old fish they talked to earlier.
- 34:26That's just another random old fish
- 34:27passing by. They keep looking, they find
- 34:30the old wise fish, and bring him to the
- 34:32frog. They watch the frog swimming
- 34:34lessons and that's the day they finally
- 34:36understand water and swimming. The two
- 34:39fish buy a GoPro and invite their big
- 34:41fish friend to record YouTube videos to
- 34:44give swimming tips to the world. The
- 34:46frog joined and built a swimming app.
- 34:48Water is the medium, but it's also the
- 34:51context and the context is more
- 34:53important than most people realize.
- 34:56Here's the context for many adult
- 34:57swimmers. When they were young, the body
- 35:00could absorb late nights, alcohol, bad
- 35:03eating, overtraining, under training,
- 35:05injuries, all of it with seemingly no
- 35:08consequences. After 35, the consequences
- 35:11arrive and they keep arriving, bigger
- 35:14every year. So, they come to the water.
- 35:16Some are injured from the other sports.
- 35:19Some want to add swimming to their
- 35:21athletic skill collection. They come
- 35:23looking for flow and wellness. They find
- 35:26frustration and stagnation. They try to
- 35:28hire a knowledgeable coach, but all the
- 35:31coaches know is how to train young
- 35:33swimmers. Young swimmers who are pure
- 35:35instinct and don't even understand their
- 35:37own movements in the water. I remember
- 35:39in 2023 when I met that famous coach, he
- 35:42told me that his adult learners ask too
- 35:45many questions. He wished they just give
- 35:47him the money and stay silent. That is
- 35:49who adult swimmers are trying to learn
- 35:51from. I was disappointed, but it got
- 35:53worse. In 2025, I created a chat group
- 35:56with more than 500 coaches from
- 35:59different countries. Those were some of
- 36:01the most open-minded coaches, but
- 36:02through them I also learned that most
- 36:04coaches are not like that. Most are not
- 36:07only close-minded, but they also
- 36:09sabotage swimming as a sport, as a
- 36:11healthy exercise, or even as a personal
- 36:14and community improvement path. I
- 36:16learned that swimming is not all fun.
- 36:18For some swimmers, it can become a
- 36:20nightmare. Later that year, a swimmer at
- 36:22a camp in Italy asked a question I
- 36:25didn't have an answer to. A question I
- 36:27would try to answer for the next 10
- 36:28years. How do you, as a swim coach,
- 36:31offer meaning beyond gold medals? You
- 36:33remember Lochte selling his Olympic
- 36:35medals, Popovich melting his, the common
- 36:38Olympic blues, my college friends with
- 36:41their trunks full of NCAA trophies
- 36:43crying on the side of the road on the
- 36:45drive back home.
- 36:46Then Iris, another mentee, asked another
- 36:50hard question. I want to improve, but I
- 36:52feel like now focusing on getting better
- 36:54is taking some of the fun out of
- 36:56swimming. How do I balance trying to
- 36:58improve while still enjoying the pool? A
- 37:00theme was becoming clear. Then the
- 37:02enhanced games happened. A competition
- 37:05where athletes are paid to break records
- 37:07using performance-enhancing drugs.
- 37:09That's what shifted everything into
- 37:10focus for you. Top swimming speed had
- 37:12become the most financially celebrated
- 37:15skill of the sport. Not because it
- 37:17offered meaning or wellness or
- 37:19community, but because it offered
- 37:21entertainment. There's nothing wrong
- 37:23with entertainment or money or swimming
- 37:25speed. But I'm telling you this from the
- 37:27future. The excess love of those things
- 37:29create ephemeral fulfillment followed by
- 37:32a lot of suffering. Chasing money,
- 37:34speed, and entertainment is what creates
- 37:36the AR problem, the bad swimming advice
- 37:39online, why so many adults leave the
- 37:41pool frustrated. It's why you send that
- 37:44letter to your 7-year-old self
- 37:46illustrated with AI images
- 37:48telling him how to become the fastest
- 37:50swimmer in the world. Don't do that
- 37:51again. Finally, is what gave birth to
- 37:54the nightmare of the Las Vegas
- 37:55competition. You have seen that chasing
- 37:58speed and money and medals is not a
- 38:00great path. But here's what the research
- 38:03says. It reveals a paradox. The athletes
- 38:06at the top of their sport are the most
- 38:08insecure people in the pool, in the gym,
- 38:11or in the field. A world-class swimmer
- 38:13ranked 20th globally can feel worse
- 38:16about their swimming than a much slower
- 38:18athlete in a small club. It's called the
- 38:20big fish little pond effect. When your
- 38:23daily reference group is the best in the
- 38:25world, your brain compares upward
- 38:28constantly and excellence stops feeling
- 38:30like excellence. Bodybuilders at a
- 38:33single digit body fat describe
- 38:34themselves as small and out of shape.
- 38:37This happens to people at the very top.
- 38:39Olympic champions like Adam Peaty,
- 38:41Amanda Beard, Michael Phelps, and many
- 38:43other world champions have all spoken
- 38:45publicly about the inner doubt that
- 38:47follows them everywhere. Studies show
- 38:50they score higher in perfectionism, but
- 38:52also report constant self-questioning
- 38:55about their own competence. The traits
- 38:57that drive them to the top,
- 38:59hyper-attention to flaws, fear of
- 39:01failure, self-worth tied to results, are
- 39:03the same traits that make them fragile.
- 39:06Beginners suffer, too, but through a
- 39:08different door. Social physical anxiety,
- 39:10the fear of being judged in the gym or
- 39:12pool, traps them in the loop. They feel
- 39:15out of shape, so they avoid exercise.
- 39:18So, they stay out of shape. Surveys
- 39:20shows that 30% to 50% of beginners
- 39:23experience meaningful gym intimidation.
- 39:25The voice in their head says they don't
- 39:27belong, that everyone is watching, that
- 39:29they should already be better. Both ends
- 39:31of the spectrum share the same root,
- 39:34self-worth tied to performance. The good
- 39:37news is that decades of research have
- 39:39mapped the healthy middle. Five things
- 39:41that consistently work at every level.
- 39:44One, evaluate behavior, not the self.
- 39:47The bad session is not a bad person.
- 39:49Anchor your motivation in mastery, in
- 39:51your own improvement instead of beating
- 39:53others. Competition is good, but as a
- 39:56tool for self-mastery, not as the
- 39:58primary goal. Practice gratefulness.
- 40:00Protect a stable sense of self-worth
- 40:03that doesn't rise and fall with
- 40:04outcomes. And build an identity outside
- 40:07of the sport, so one bad day doesn't
- 40:10shake who you are. The research is
- 40:12clear. High standards do not require
- 40:14self-punishment. The athletes who last
- 40:17and the ones who enjoy the work, are the
- 40:19ones who learn to separate what they do
- 40:21from who they are. One of the greatest
- 40:23achievements as a coach was stopping
- 40:25myself from achieving performance and
- 40:28letting the team play around in the pool
- 40:30for the last 30 minutes of the workout.
- 40:32Of all the things we have taught them,
- 40:34backing off and giving them time to play
- 40:37was the healthiest thing I have done for
- 40:39them. Not only this year, but for years
- 40:42to come, they'll remember playing in the
- 40:43pool. If you want to teach adults how to
- 40:45swim better, the context matters more
- 40:48than the instructions. Adults are not
- 40:50bad swimming students. They're never
- 40:52been given the time and proper
- 40:55instruction to learn. Derek came into
- 40:57the camp open to the possibility of
- 40:59improving his swimming after years of
- 41:01trying everything.
- 41:02When he saw the data, with 30%
- 41:05propulsion, most of his arm movement was
- 41:07wasted not pushing him forward, he was
- 41:10shocked. Here's the context. He is a
- 41:12physician. He understands the human
- 41:14body. As soon as we gave him the data,
- 41:17the video, and some tips, something
- 41:19clicked. 24 hours later, we measured
- 41:22again. 50% propulsion. After a five-day
- 41:25swim camp, he swam 20 seconds faster.
- 41:27Here's my context. Contrary to popular
- 41:30belief, I don't love swimming that much.
- 41:32I don't even love the water. What I
- 41:34always loved, and the people I've always
- 41:36interacted best with, are the ones who
- 41:38want to become aqua sapiens. People who
- 41:40use their skills and their talents to
- 41:43seek wisdom through human movement in
- 41:45the water. That's your context. That's
- 41:47the only thing that hasn't changed,
- 41:49regardless of how fast you can swim, how
- 41:52old you are, how many teammates you
- 41:54have. People who only love results run
- 41:57away from skills and talents. People who
- 41:59love the process swim closer and closer
- 42:01to it. People who just care about
- 42:03results clicked, but stopped watching
- 42:05this video a long time ago. Speaking of
- 42:07running way, runners are the the who
- 42:10struggle with tip number five, the most.
- 42:18The most important context adults bring
- 42:20to the pool is their past sport.
- 42:22Swimming is a lot easier if you did one
- 42:24of these sports before. Rowing. Hip to
- 42:26arm sequencing, pull timing, and breath
- 42:29cadence mirror the freestyle stroke
- 42:31cycle almost directly. Plus, it gives an
- 42:34intuitive understanding of how
- 42:35increasing speed also increases the
- 42:37resistance of water. Climbing. Grip
- 42:39strength and full body tension transfer
- 42:41to the pool. Plus, the arm strength
- 42:43generated by climbing is unmatched.
- 42:46Martial arts. Breath timing, hip
- 42:47rotation as the engine, and the full
- 42:49body coordination under pressure.
- 42:51Martial artists already know the nervous
- 42:53system is the real opponent. Seven,
- 42:55yoga. Breath control, flexibility, and
- 42:57proprioception are critical skills that
- 42:59are also used in swimming. Number six,
- 43:01surfing. Reading water, hip rotation,
- 43:04and breath control under pressure on an
- 43:06unstable surface build true aquatic
- 43:08intuition. Plus, the mechanics of
- 43:10pulling your body through the water are
- 43:12all there. Number five, water polo.
- 43:15In-water conditioning, treading water,
- 43:17and breath control under fatigue.
- 43:19Though, the vertical position can fight
- 43:21horizontal balance. Number four, ballet.
- 43:23Posture, rhythm, core control, and
- 43:25kinesthetic awareness translate directly
- 43:28into the body discipline of horizontal
- 43:30water movement. Number three,
- 43:31gymnastics. Body tension, spatial
- 43:34awareness without much visual feedback,
- 43:36shoulder strength, and core control are
- 43:39the foundations of many water skills,
- 43:42including streamlining and underwater
- 43:44work. Hanging and arm relative strength
- 43:46are also extremely transferable. Number
- 43:49two, free diving.
- 43:50Breath control, swim kicks, relaxation,
- 43:53and CO2 tolerance overlap almost
- 43:55completely with swimming fundamentals.
- 43:58Before I tell you the last one, look at
- 43:59the list again. What do most of them
- 44:02share? Supple feet. Number nine,
- 44:04climbing shoes compress the foot into a
- 44:06downward point, building the same toe
- 44:09strength and arch engagement that
- 44:11swimmers need. Martial arts, barefoot on
- 44:14the mat, pivoting and grounding through
- 44:16the feet for every kick, stance, and
- 44:18rotation. Yoga, practice barefoot with
- 44:20toes spread and actively gripping the
- 44:23mat. Yoga systematically reopens the
- 44:26ankle range that years of shoes have
- 44:28closed off. Surfing, the foot is
- 44:30constantly reading and gripping an
- 44:33unstable surface barefoot. That
- 44:35life-foot connection builds the ankle
- 44:37sensitivity swimmers need to feel the
- 44:39water through the kick. Water polo,
- 44:41treading water for an entire game means
- 44:44the foot and ankle are articulating
- 44:46continuously under load. The eggbeater
- 44:48kick alone builds more ankle mobility
- 44:51than most dry land sports combined.
- 44:53Ballet, point shoes and relentless
- 44:55pointing repetition build the strongest,
- 44:57most articulate feet of any sport on the
- 45:00list. Ballet dancers have some of the
- 45:02closest foot profile of elite swimmers.
- 45:04Gymnastics, pointed toes are scored.
- 45:07Bare feet on the floor, beam, and vault
- 45:10develop foot control and proprioception.
- 45:13Gymnasts instinctively know where their
- 45:15feet are in space. So do the best
- 45:17swimmers. Free divers train their feet
- 45:19to be loose and powerful at the same
- 45:21time. The exact paradox swimming
- 45:23demands. Rowing, the exception. The only
- 45:26sport on the list where the foot is
- 45:28strapped in and largely passive. Now
- 45:30that you know supple feet are the key,
- 45:32can you guess what number one is? Look
- 45:34at the top eight again. Barefoot,
- 45:37barefoot, barefoot, barefoot, barefoot,
- 45:39barefoot, fins or barefoot, and number
- 45:42one is also barefoot. Artistic swimming,
- 45:44full body undulation, precise timing,
- 45:47core engagement, rhythm, CO2 tolerance,
- 45:50hand proprioception overhead, and an
- 45:52understanding of balance on every plane
- 45:54in the water. The feet are the key
- 45:56element of this sport. Pointed toes, toe
- 45:59spread, ankle articulation, not
- 46:01optional, Scored. No sport produces a
- 46:04more competitive or smooth swim ready
- 46:06foot. The number one reason adults
- 46:08struggle to swim smoothly is their feet.
- 46:11It's like trying to drive smoothly while
- 46:13pressing the accelerator and the brakes
- 46:15the whole time. Some adults more
- 46:16intensely than others. This is the most
- 46:18underrated swimming skill in the
- 46:20internet in 2026. Two reasons. First,
- 46:23because it's not easy to improve and
- 46:24I'll tell you exactly how long it takes
- 46:26to see the difference according to the
- 46:28studies. And second, because most people
- 46:30can't see how much it matters. But if
- 46:32you remember tip number one, you can
- 46:34already see the magnitude of the
- 46:35problem. In swimming, ankles stuck in
- 46:38dorsiflexion add 10 to 25% drag. That
- 46:41means if you swim at 1:37 per 100 m, you
- 46:44could be swimming about 7 seconds faster
- 46:46with the same effort. Just from suppler
- 46:49feet. A study of 10 NCAA Division 1
- 46:52swimmers ranked the variables that
- 46:54predict kicking speed. Vertical jump
- 46:56power didn't matter too much. Body size
- 46:58didn't matter much. Ankle flexibility
- 47:01beat them both. Ankle flexibility beats
- 47:03raw power. Here are three things that
- 47:05kids do that adult swimmers usually
- 47:08don't. They spend more time barefoot.
- 47:11They spend more time on the ground. And
- 47:13they use fins more often. That's why
- 47:15their feet grow supple while adults stay
- 47:18stuck. So, what should you do? The
- 47:20research and the coaching practice
- 47:22converge on the four-part approach. One,
- 47:25kick without fins to build the movement
- 47:27pattern. For some swimmers with an
- 47:29efficient kick, the fastest way to
- 47:31improve ankle mobility is to just kick
- 47:33with a kickboard more. Two, swim with
- 47:35fins. Long, short, soft, hard, they all
- 47:38work. We recommend the ones we put in
- 47:40the description. The extra surface area
- 47:42of the fins forces ankle extension
- 47:45during the power phase, passively
- 47:47stretching the ankle through the full
- 47:49range underwater. Three, dryland work.
- 47:51Specifically, the ankles routine. Daily
- 47:54is better. Twice per week is the
- 47:56minimum. strengthening alongside
- 47:58stretching. So the new range of motion
- 48:00is stable and usable. The honest truth
- 48:03about timeline. A 6-week study on 20
- 48:05competitive swimmers measured plantar
- 48:07flexion before and after intervention,
- 48:10but the improvements in 25-m kick times
- 48:12were not statistically significant. That
- 48:15confirms the pattern. The ankle opens up
- 48:17in weeks. The body needs longer to learn
- 48:20how to use the new range under load. We
- 48:22have seen significant and permanent
- 48:24results in just 7 months. Fins are the
- 48:27fastest and easiest path because they
- 48:29combine stretching with swimming
- 48:31specific movement, but fins alone won't
- 48:33fix severely restricted ankles built
- 48:36over decades. You need the dry land work
- 48:38alongside the water work. A lasting
- 48:41change in the tissue takes closer to 7
- 48:43months of consistent practice. It sounds
- 48:46like a lot, but consider this trade. If
- 48:48you swap 20% of your swimming time for
- 48:51dedicated foot work, you can swim faster
- 48:54with the same effort. Smoother and
- 48:56healthier feet mean better knees, hips,
- 48:59and lower back for the rest of your
- 49:01life. The human foot is a work of art.
- 49:04It wants to feel free. It's the
- 49:06foundation of the human body. So tip
- 49:08number five, if your feet are not as
- 49:10mobile, you're not slow because you lack
- 49:13power. You're slow because you're
- 49:14driving with the brakes on. Release the
- 49:16brakes. So how do you float like a
- 49:18butterfly and swim like a fish? Chase
- 49:21weightlessness. Move your guts up. Use
- 49:23your inner life jacket. Close your eyes
- 49:26and release the brakes. The next time
- 49:28you get in the pool, run them in this
- 49:30order. Float first for 5 to 20 minutes.
- 49:33Move forward second the rest of the
- 49:35time. Pay attention to which one is the
- 49:38hardest for you. That's where your
- 49:39attention should be focused on. I know
- 49:41you'll have more questions after this
- 49:43letter.
- 49:44Read the comments and send me the best
- 49:46ones for next time. We'll do it as a
- 49:48team of aqua sapiens. Take care.
- 49:50Sincerely, you from 2036. After reading
- 49:54this letter, here's what I've learned.
- 49:56If you're not as good a swimmer as you
- 49:58would like, zoom out and see your
- 50:00context. You're a human. The first men's
- 50:03world record for the 1500 was set in
- 50:061908 at a 1:31 pace per 100 m. The first
- 50:11women's record came in 1922 at 1:40
- 50:14pace. Those were the fastest humans on
- 50:16the planet. Today, those paces are
- 50:19within reach of dedicated adult amateurs
- 50:22in clubs all over the world. You're a
- 50:24better swimmer than most Homo sapiens
- 50:27who have ever lived. Appreciate that and
- 50:29keep exploring like a true aqua sapiens.
- 50:32You're already standing near the top of
- 50:35the mountain. Turn around, enjoy the
- 50:37view, and start walking backwards.
- 50:39Ideally, barefoot. It's good for your
- 50:41feet and your knees. What questions
- 50:44would you want me to ask me from the
- 50:46future? I've already have one question.
- 50:48What advice would you give us to improve
- 50:50the S&T app exponentially? If you like
- 50:53these drawings, I will refuse to sell
- 50:55them. I will give them away to the
- 50:57people who clearly enjoy our work and
- 50:59are improving their skills inside the
- 51:01Skills with N T app. See you there. Swim
- 51:03with skills.
