Is There a Hypertrophy Zone? (Well....not really but kind of) — Transcript
Full transcript
- 0:05So once again, while I'm trying to put
- 0:06together something a little bit more
- 0:07involved, I want to take one of my very
- 0:10old articles originally published in
- 0:112016 and put it in video format because
- 0:13let's face it, the kids today don't read
- 0:16articles. And what I want to address is
- 0:19the question, is there a hypertrophy
- 0:22zone in terms of repetitions per set? We
- 0:26start as always with a story and a
- 0:29little bit of history.
- 0:33So when I graduated from UCLA in 1993,
- 0:37and by the way, Jackson, my degree was
- 0:38in physiology, not exercise science. So
- 0:42spare me the [ __ ] ad homonyms and
- 0:43either address my criticisms directly
- 0:46and apologize or please feel free to
- 0:48shut the [ __ ] up. Anyway, when I
- 0:51graduated, like all good college
- 0:53graduates, I knew I knew everything.
- 0:55>> [laughter]
- 0:55>> Ha.
- 0:58Yeah. Ah, youth. One of the things we
- 1:01had been taught was that the hypertrophy
- 1:05range in terms of repetitions per set,
- 1:07the number of repetitions that optimally
- 1:09stimulated muscle growth was 8 to 12.
- 1:12And this value has kicked around for
- 1:14decades.
- 1:16Endless books from textbooks to
- 1:19practical books, many of which I have on
- 1:21on my shelf, uh, repeat this number. And
- 1:24none of them that I can recall has ever
- 1:26had a reference for it. It's just one of
- 1:28those values that's
- 1:31been repeated so many times that it's
- 1:33true by repetition. Except, as you'll
- 1:36see, it's not. [snorts]
- 1:40Now, somewhere shortly thereafter, I
- 1:42would go take the United States
- 1:43Weightlifting Federation level one
- 1:45certification because I was interested
- 1:46in everything, including Olympic
- 1:47lifting. And at that class, Wes Barnett,
- 1:50who was one of the top US lifters of the
- 1:52day, uh definitely stood out because he
- 1:54was he was a big dude. So I asked the
- 1:57coach, "Hey, what is what does Wes do,
- 2:00you know, for for quad size, for
- 2:01hypertrophy?" And the coach said, "Oh,
- 2:03just lots of sets of fives."
- 2:06What? I knew that 8 to 12 was the
- 2:09hypertrophy range. How could sets of
- 2:11five possibly work? And what that told
- 2:14me is that maybe, just maybe, there was
- 2:17a little more to that story.
- 2:22Like I said, if you look at books in
- 2:24like the 80s and 90s when we were
- 2:26starting to scientific scientificize
- 2:28this [ __ ] you'll just see 8 to12 listed
- 2:30as the hypertrophy range. And as I
- 2:32stated, no one ever seemed to have a
- 2:35direct reference. It was just one book
- 2:36citing a paper, citing another book.
- 2:38It's what I call the reference circle
- 2:40jerk, not to be confused with the
- 2:41fitness industry circle jerk. But where
- 2:43did that value come from? Well, I have a
- 2:45hypothesis and that's all that it is.
- 2:48You go back even further to the lifters
- 2:51of the 50s, the 60s, and the 70s. Um, a
- 2:54common recommendation was to do three
- 2:56sets of 10 of every exercise. Somewhere
- 2:58on my shelf, I've got Steve Reeves
- 3:00training book. And even then, three sets
- 3:02of 10. And that derives from Delor. Go
- 3:04look it up, kids. I've also got his his
- 3:07book on my shelf because I'm a nerd.
- 3:08Anyway, and what I here's what I think
- 3:10happened. uh bodybuilders were doing
- 3:12three sets of 10 and uh like the best of
- 3:15us uh lost count on repetitions and
- 3:17sometimes they did eight and sometimes
- 3:19they got 12 and voila 8 to 12 became the
- 3:23hypertrophy zone. That may or may not be
- 3:26right. That's my best guess. If anyone
- 3:28has a clue, please please let me know.
- 3:30Um because I've I've never seen a value.
- 3:32In any event, that value was just stated
- 3:35and restated most places for years.
- 3:41Now over time that would start to change
- 3:44and I think by I don't know late 80s
- 3:47even the early 90s I think the the
- 3:49hypertrophy range had been expanded
- 3:51depending on what you were reading to
- 3:53maybe you know 8 to 15 6 to 15
- 3:56repetitions frequently you'd see this
- 3:58done in like a pyramid style you know 15
- 4:0112 10 8 and maybe then a final set of
- 4:04six things of that nature but is still
- 4:06kind of in that range
- 4:09at At the same time, there was something
- 4:11called the repetition continuum. And
- 4:12actually, this wasn't in my original
- 4:14article that basically said different
- 4:17repetition ranges had very different
- 4:19physiological effect. And it simple form
- 4:22simplest form, it looked like this. Uh
- 4:23between 1 to five repetition maximum,
- 4:25that was strength. 8 to 12 repetition
- 4:27maximum, hypertrophy. 15 plus repetition
- 4:31maximum, muscular endurance, the
- 4:34continuum of repetitions, the original
- 4:36repetition continuum. And it was seen as
- 4:38these very very very discreet
- 4:41categories.
- 4:43And as I'll come back to, there is
- 4:44there's an element of truth to that. But
- 4:47as we would come to find out going
- 4:49forwards, that was simplistic or it was
- 4:53sorry, it was overly simplistic, but
- 4:55more to the point it was incomplete.
- 5:01And making a quick tangent, you know,
- 5:02something I never do. At some point on
- 5:05my website, I also wrote this article
- 5:06and I said, "If if you had to pick a
- 5:09single repetition range to optimize
- 5:11hypertrophy, what would it be?" And I
- 5:13actually asked my training partner this
- 5:15back in the 90s, a really smart guy, and
- 5:16he came with the same answer. And the
- 5:18answer was sets of five to eight. And
- 5:20the rationale for that actually builds
- 5:22upon that video I did on effective reps
- 5:24a few weeks ago that apparently some
- 5:26people didn't agree with. And I I might
- 5:28redress it or or I might not. Um
- 5:30although I've actually come across
- 5:31another interesting model similar but
- 5:34but a little bit more nuanced. But
- 5:36anyway uh my rationale had to do with
- 5:39the fact that somewhere between 80 and
- 5:4185% of max about a 5 to8 rep max you
- 5:43will get full fiber recruitment from the
- 5:45first repetition.
- 5:48By doing sets of five to eight in that
- 5:50intensity range that also ensures that
- 5:52well you will get the most repetitions
- 5:55per set at full recruitment. and realize
- 5:58I wrote that years before and asked that
- 6:01question years before the effect of reps
- 6:02framework any of that had ever even been
- 6:06considered or suggested that came much
- 6:08later. Borch vagerly blade wasn't
- 6:11talking about that till stimulating reps
- 6:13till the 2000s.
- 6:15So that was my logic. If you are trying
- 6:18to get the maximum number of repetitions
- 6:20per set, like the most efficiently, that
- 6:23would be the best place to do it because
- 6:24let's say you move to triples, yeah, you
- 6:27will get no more fiber recruitment
- 6:30because rate coding is what's increasing
- 6:32force output, but you will do far few
- 6:35far fewer repetitions per set. Now, if
- 6:37you go to say 15 set of 15 at maximum to
- 6:40failure, zero reps in reserve, you will
- 6:43eventually you won't get full fiber
- 6:44recruitment till about rep 10 or 11. So,
- 6:46you're doing a bunch of other
- 6:48repetitions beforehand. So, again, this
- 6:50was a thought piece. I wasn't saying
- 6:52only do sets of five to eight. I'll come
- 6:54back to this in a second. I was asking
- 6:57the question if you had to pick a single
- 6:59repetition range. And I mention this now
- 7:02because I guess the current idea based
- 7:04on similar concepts is that you should
- 7:06only do sets of four to six for
- 7:08hypertrophy, which is myopic to the nth
- 7:11degree. I understand the physiological
- 7:14logic that they're applying. It's very
- 7:16similar to mine, but it's missing just a
- 7:18couple of nuances in practical training.
- 7:20And I'll just give you a simple one. I
- 7:22want any of these people recommending
- 7:24that to show me a dumbbell lateral raise
- 7:27for a set of four to six, please. Done.
- 7:30Well, um, I'll come back to that, but I
- 7:34kind of brought up a point there.
- 7:38Again, that five date value, that was a
- 7:40thought piece. It wasn't meant to be a
- 7:42recommendation as you'll see why that's
- 7:45the case. But I mentioned in this last
- 7:46section that you know you could do
- 7:48triples but you'd be getting less
- 7:50repetitions per set. I mean see you have
- 7:52to do more total sets to get the same
- 7:55number of repetitions under full
- 7:57recruitment. Maybe I'll stop using the
- 7:59terms effective reps because it seems to
- 8:01cause people a lot of mental trauma. Hi
- 8:03Greg. Anyway, think back to the West
- 8:05Barnett story. Even Charles Polloquin
- 8:07said this that low repetition sets could
- 8:09stimulate hypertrophy if you did enough
- 8:12of them. And that sort of brings me to
- 8:15the next point because there would be a
- 8:17paper coming out of Brad's lab for
- 8:20whatever that may be worth now that
- 8:22looked at seven sets of three, I don't
- 8:25know, 85 90% of max something in that
- 8:27range. I'm not pulling it to three sets
- 8:29of 10 in the more typical hypertrophy
- 8:31zone. And it found that growth was the
- 8:33was identical. And if you look at that
- 8:37in terms of the number of repetitions
- 8:39done under maximum recruitment, well,
- 8:42seven sets of three is going to give you
- 8:4321 repetitions under conditions of
- 8:45maximum recruitment. Three sets of 10,
- 8:47assuming they were to to zero reps in
- 8:50reserve, four to five reps per set under
- 8:52conditions of maximum recruitment,
- 8:53you're looking at 12 to 15 repetitions.
- 8:56And I bet that comparison over the short
- 8:58term would generate no no differences in
- 9:01growth. 15 and 21 are just too close.
- 9:04So, seven sets of three did work to
- 9:06generate hypertrophy. And I imagine if
- 9:08I'd thought to ask West Barnett's coach
- 9:10how many sets of five he did for
- 9:12hypertrophy, it was probably, you know,
- 9:15four, five, six sets, somewhere in that
- 9:17range.
- 9:21Oh, fun fact, piece of trivia. You know
- 9:23where 5x5 came from? When Bill Starr
- 9:26wrote only the strong shall survive,
- 9:28Atha had done a massive review that said
- 9:30you got the best strength gains doing
- 9:32between four to six sets of four to six
- 9:34repetitions. Because he was working with
- 9:36football players, Star just rounded that
- 9:38off to 5x5. Also, that's the reason we
- 9:41like five rep sets. That's why, guys. As
- 9:44usual, I digress.
- 9:49So, it was clear that low reps could
- 9:51stimulate hypertrophy as moderate
- 9:54repetitions so long as you did enough
- 9:56total sets. Hold that thought. Later
- 9:59work would come out looking at the low
- 10:02load stuff and also blood flow
- 10:04restriction which is very similar
- 10:06showing that three sets of 30 at like 25
- 10:10to 30% of max done to physiological
- 10:13failure could cause the same growth as
- 10:17moderate repetition ranges. And I still
- 10:19maintain that the reason being that
- 10:21three sets of 30 to failure means you
- 10:22get five reps under maximal recruitment
- 10:25at the end of each set which is 15. And
- 10:27that's the same roughly the same as
- 10:29three sets of 10 to failure. Volume load
- 10:32doesn't equate them. Total reps doesn't
- 10:33equate them. It's the same number of
- 10:35sets for what little that means. It's
- 10:37the same number of total repetitions
- 10:39under maximum recruitment.
- 10:42Regardless, this kind of changed the
- 10:44model or the recommendations.
- 10:51So in the aggregate, the data seemed to
- 10:53be suggesting that repetition count
- 10:54almost didn't matter. Although there was
- 10:57one slight nuance and I mentioned this
- 10:58in the video whose title I won't name
- 11:00that had to do with the number of
- 11:03repetitions under maximum recruitment.
- 11:04Again I don't want to I don't want to
- 11:06cause people mental stress. When you
- 11:08were doing heavy sets above say about
- 11:1180% of maximum you did not have to go to
- 11:14zero reps in reserve. And that was
- 11:15because the when the weight's heavy
- 11:17enough you are getting maximum
- 11:19recruitment early enough to get
- 11:20repetitions under maximum recruitment.
- 11:23same time when you're doing high
- 11:25repetitions you did have to go to zero
- 11:27reps in reserve because you don't get to
- 11:29maximum recruitment till those final
- 11:31four or five repetitions which is also
- 11:34given that fact is why I don't
- 11:36understand why people have a such
- 11:38problem with this model I or better yet
- 11:42propose a better model please I don't
- 11:46when I do a follow-up video so that was
- 11:48one nuance there was another but I'm
- 11:50going to come back to that in a
- 11:54Now, one of the genius conclusions from
- 11:56this data, which is true in in the most
- 11:59literal sense, is that hey, repetition
- 12:02count doesn't matter for hypertrophy.
- 12:04Mr. Mike Isertell and his fantastic
- 12:07a new AI book or somewhere else gave no
- 12:10more training recommendations than that.
- 12:13Repount doesn't matter. Now, in a
- 12:14physiological sense, that that's
- 12:16apparently true, and I'm not saying it's
- 12:18not, but it ignores a lot of details and
- 12:21a lot of nuance and a lot of
- 12:22practicality. Let's look at a few before
- 12:26I sort of come back and and try to get
- 12:28to the point. While that low rep study,
- 12:30the seven sets of three versus three
- 12:31sets of 10 did show the same growth with
- 12:33lots of low rep sets, the 7 by3 group
- 12:36took enormously longer to complete the
- 12:39sets. If you're looking at 7 by3, even
- 12:41on a two-minute rest interval, and 3
- 12:43minutes is probably better. you're
- 12:44looking at 20 minutes to get if you want
- 12:45exercise. 3x 10 with a two-minute rest
- 12:48interval, it's about 9 minutes and then
- 12:50you can go do something else.
- 12:53Also, I think forgotten was that there
- 12:55were a couple injuries in the low rep
- 12:57group. Doing lots and lots and lots of
- 12:59heavy low repetition work doesn't work
- 13:02well for a lot of people depending on
- 13:04how they were physically built. So,
- 13:06yeah, in a physiological sense it
- 13:08worked, but in a practical sense it
- 13:10didn't work. Also, you really have to
- 13:12consider exercise selection here. I'm
- 13:14sure Wes Barnett when he was building
- 13:16his gigantic quads was doing sets of
- 13:18five in the back squat, something he was
- 13:19extremely good at. Um, please send me a
- 13:23video of you doing seven allout sets of
- 13:25three in the leg extension. Because
- 13:27while I've seen people claim that their
- 13:28knees shot across the gym, I've never
- 13:30seen it happen in real life. As I'll
- 13:33come back to, certain exercises lend
- 13:35themselves to a greater or lesser degree
- 13:38to different repetition counts. jumping
- 13:40to the high rep work that three sets of
- 13:4330 the low load stuff and blood flow
- 13:44restriction is is similar. I know I
- 13:46didn't describe it but the same dynamics
- 13:49basically hold it lets you use light
- 13:51loads
- 13:52as long as you actually don't have to go
- 13:54to physiological muscular failure for
- 13:56reasons which basically the body will
- 13:58recruit
- 14:00the the highest threshold motor units
- 14:02the type two fibers earlier in the set
- 14:03so you get more repetitions under full
- 14:06recruitment. What is the [ __ ] problem
- 14:07with the model guys? Anyway, it takes a
- 14:10longer time. It's also extremely
- 14:12painful. And I believe in a couple of
- 14:14those studies, people threw up, right?
- 14:17You can prove this to yourself. Go do
- 14:19three sets of 30 to zero reps reserve in
- 14:21the leg extension. And you tell me, you
- 14:23tell me what that feels like. Not to
- 14:25mention that for certain movements, big
- 14:28compound barbell stuff, good luck. Good
- 14:31luck doing three sets of 30 to zero reps
- 14:33in reserve, right? People often don't
- 14:35realize that these studies for control
- 14:37purposes tend to use highly controlled
- 14:39exercises in the low load stuff. It's
- 14:42typically [ __ ] like leg extensions
- 14:44because that can be that can be done
- 14:45safely for three sets of 30. You're not
- 14:48going to do like I said a barbell back
- 14:50squat or certainly not a front squat or
- 14:52many many movements for three sets of 30
- 14:55to zero reps in reserve. That's a
- 14:57practical thing. And then somewhere in
- 14:58the middle you split the middle.
- 15:04Before wrapping up, let me revisit that
- 15:06repetition continuing. So in its
- 15:07original version, it was very specific.
- 15:115 RM or less maximum strength. 8 to 12
- 15:14RM muscle hypertrophy. 15 plus RM
- 15:18muscular endurance. Clearly that's not
- 15:20true. Clearly hypertrophy muscle growth
- 15:23can be generated from very low to very
- 15:26high repetition ranges possibly a range
- 15:28of three to 30. I mean I guess in
- 15:30premise if you could do enough heavy
- 15:32singles that might work. I don't know.
- 15:35The only study only did five and it
- 15:37didn't generate any growth. But like
- 15:38maybe if you did 30 max singles it would
- 15:41be extremely timeefficient and extremely
- 15:43joint unpleasant. But it it might work.
- 15:45I wouldn't recommend it regardless. We
- 15:48know that the hypertrophy zone is
- 15:50extremely broad, but what about those
- 15:52other adaptations? What you do generally
- 15:54see is specific adaptations in terms of
- 15:58both maximal strength and muscular
- 16:00endurance at the repetition ranges
- 16:04from the original continuum. Say sets of
- 16:06five and less. Yes, they can generate
- 16:09hypertrophy feed enough sets, but they
- 16:11also tend to improve maximal strength
- 16:13the most because maximal strength and
- 16:15performance have there's also
- 16:17neurological factors and technical
- 16:19factors and things of that nature that
- 16:21that play a role in how much you can
- 16:23actually lift. So, while they can
- 16:25generate hypertrophy, they still have a
- 16:27predominating effect
- 16:29comparatively. But those sets of five
- 16:31generally don't improve muscular
- 16:32endurance much. It's a little more
- 16:33complicated as with absolute versus
- 16:35relative muscular endurance and you
- 16:37don't want to get into it. But by and
- 16:38large now jumping to the high repetition
- 16:40stuff, the sets of 30, the low load, the
- 16:42BFR, you don't see nearly as much
- 16:44increase in maximal strength. Now I
- 16:46realize there's some studies that show
- 16:47that's not true and it's always pretty
- 16:48much in untrained and isolated
- 16:50movements. We're talking about, you
- 16:52know, real movements, not the case. But
- 16:54it improves muscular endurance better.
- 16:56And then in the middle that hypertrophy
- 16:59range which I'm going to deci define now
- 17:00but is between six and 15 and you'll see
- 17:03why. At the lower end say 6 to 10 you
- 17:06get hypertrophy more maximal strength
- 17:09less maximum less muscular endurance and
- 17:12in the higher repetition ranges 10 to 15
- 17:14hypertrophy
- 17:16relatively more of improvement in
- 17:17muscular endurance and less maximum
- 17:19strength. So the best way to think of
- 17:21this is that each of these ranges 1:5, 6
- 17:24to 15, 15 to 30
- 17:27not only has its own direct effects, but
- 17:30affects the rep range next to it. So 1:5
- 17:34will overlap a little bit with say the 6
- 17:36to 10. 6 to 10 will overlap with 1:5. 6
- 17:38to 10 will overlap with 10 to 15. 10 to
- 17:4115 will overlap with 6 to 10. 10 to 11
- 17:4315 and up. And then 15 and up will
- 17:45overlap. Get it? So the rep continuum
- 17:48there is still elements of truth to it.
- 17:50The big change being that the
- 17:52hypertrophy zone is much broader but
- 17:55fives and below still going to be better
- 17:56for maximal strength. 15 and up local
- 17:59muscular endurance in the middle you
- 18:01split the middle. So let's answer the
- 18:03original question.
- 18:07So is there a hypertrophy zone? In the
- 18:11purest physiological sense the answer is
- 18:14clearly no.
- 18:16Clearly a much broader repetition range
- 18:19than the old 8 to 12 or even the 6 to 15
- 18:22can generate hypertrophy. Do enough sets
- 18:25of five, you can get hypertrophy. Do
- 18:27enough sets of three, you get
- 18:29hypertrophy. In theory, I guess do
- 18:31enough sets of one, you might get there.
- 18:33I wouldn't recommend it. Do sets of 15,
- 18:3725, 30. There is a lower range once you
- 18:40get below a certain low intensity which
- 18:42about 20% of 1RM which essentially
- 18:44becomes aerobic for all practical
- 18:46purposes. You you [snorts] you're not
- 18:49really going to get a whole lot out of
- 18:50it. But somewhere between like 30% of
- 18:52maximum and like 90% of maximum 1RM
- 18:56you're you're going to you can get
- 18:57hypertrophy assuming you meet certain
- 19:00other criteria
- 19:02in my what I think is the best framework
- 19:05enough repetitions under maximal
- 19:08recruitment if you're looking at muscle
- 19:10growth maximizing muscle growth in the
- 19:14entire muscle. So physiologically it's
- 19:16clear that the answer is no within a
- 19:18fairly broad range.
- 19:22But I still argue and this is what I did
- 19:24in my 2016 article that there's still a
- 19:26practical hypertrophy zone which I tend
- 19:28to define somewhere between six and 15
- 19:30repetitions.
- 19:31And by practical I mean doing lots and
- 19:34lots and lots of sets of five which will
- 19:36work. Takes a lot of time because the
- 19:40rest intervals have to be longer. It is
- 19:43harder on the joints and not everyone is
- 19:45built for that kind of heavy low rep
- 19:48work. Some are and they love it or you
- 19:51can when every time power building comes
- 19:52back in and you want to you know look as
- 19:54strong as you are big or whatever
- 19:56whatever nonsense but not everyone is
- 19:58built for that. Even sixes can be
- 20:00pushing it but for those folks again
- 20:04somewhere between six and 15. So can
- 20:06fives build hypertrophy? Yes, but not
- 20:08everyone's built for it. And more
- 20:09importantly, not all exercises lend
- 20:10themsel to it. Generally, compound
- 20:13movements. No, I wouldn't even say
- 20:14generally. Yeah, generally compound
- 20:16movements will be better for fives.
- 20:18Barbell movements, you could do hack
- 20:19squats, leg presses, machine, chest
- 20:21press for fives. Like, if you're
- 20:23extremely skilled, you could probably do
- 20:26a lateral raise machine for fives. And I
- 20:28say that because I've done it, but I've
- 20:30spent 40 years as a a form psycho making
- 20:33sure I never break. But most people will
- 20:35not. And certainly dumb lateral raise,
- 20:36good luck. it. There'll be somebody out
- 20:39there who can do it, but the majority
- 20:40know
- 20:43at the high rep end once you get into
- 20:45that 2530 that low low stuff.
- 20:49In my opinion, it's very time
- 20:51inefficient to get those five
- 20:55reps at maximal recruitment.
- 20:58You have to basically dick around for 20
- 21:00to 25 first. It's very painful.
- 21:04People throw up. It's great for
- 21:05depletion work. in my UD2, my ultimate
- 21:08diet too, uh, high reps and stuff like
- 21:10that. But yeah, does it stimulate
- 21:12hypertrophy? Yeah. Are most people going
- 21:14to push themselves that hard? No. Might
- 21:16be useful if someone had a joint injury.
- 21:18Same with blood flow restriction because
- 21:20you can get a similar effect with less
- 21:22absolute loading, which is means less
- 21:24joint strain, but in general, I think
- 21:27it's very timeefficient. And as I
- 21:29mentioned, you're not doing that for a
- 21:32lot of compound barbell stuff. I mean,
- 21:34yeah, you can do high rep sets of leg
- 21:36press. I've seen people, you know, fart
- 21:38around through 30 quick reps
- 21:39accomplishing nothing, but to actual
- 21:41zero reps reserve, you're going to go
- 21:43throw up afterwards. Done correctly.
- 21:45Same thing with hacks. Same thing with,
- 21:47yeah, you can do machine chest. It can
- 21:49be done, but the big barbell movements
- 21:52and anything technical will not lend
- 21:54itself to sets of 30. 6 to 15, that's to
- 21:58me is the sweet spot. It's not the
- 22:01physiological hypertrophy zone. It's the
- 22:03practical hypertrophy zone. So you have
- 22:06six to 10 repetitions, which is more
- 22:08similar than not to fives. And you got
- 22:1010 to 15 repetitions, which is more
- 22:13similar than not to the the higher rep
- 22:16stuff in terms of how long it might take
- 22:20take, the physiological demands, what
- 22:22exercises might or might not be most
- 22:24appropriate. And a very time-t tested
- 22:26way of training is to combine some
- 22:29number of sets in the lower repetition
- 22:31range, which might be six to eights or
- 22:33even 8 to 10 if somebody's joints can't
- 22:34handle it or their technique falls
- 22:36apart, with some number of sets of 10 to
- 22:3812 or 12 to 15. with the 6 to10s being
- 22:42more tensionoriented and the the 10 to
- 22:4515s being more fatigue oriented even
- 22:47though they still end up at the same
- 22:49place in terms of
- 22:53maximal fiber recruitment if you you do
- 22:55it right but there are metabolic factors
- 22:57that can contribute to all of this. So
- 22:59that combination is time tested.
- 23:04Actually, one of the I I had this this
- 23:06old book years ago, Secrets of Advanced
- 23:08Bodybuilders, and it was just filled
- 23:10with mostly gibberish, but it did have
- 23:11one thing that stuck stuck out, and it
- 23:14was a
- 23:17super set. You did, you picked an
- 23:18exercise, and you did a heavy set of six
- 23:20to failure and then immediately followed
- 23:23that with a set of 20 to failure.
- 23:26tension, metabolic work for the [ __ ]
- 23:29win, guys.
- 23:34Staying in that practical range for the
- 23:36majority of your training, will give you
- 23:38the best bang for the buck in terms of
- 23:40the best stimulus. It's time efficient,
- 23:42tends to be most joint friendly. Again,
- 23:44not everyone can even handle six to
- 23:46eight. So, combine 8 to 10 and 12 to 15.
- 23:48Time- tested. 8 to 10 on your compounds,
- 23:51more complex stuff. 12 to 15 on your
- 23:53isolations. Work hard. be progressive
- 23:55over time. That is time-t tested without
- 23:58having to drop into very low rep ranges
- 24:00that your joints might not handle or
- 24:02spending time doing extremely high rep
- 24:05sets which accomplish little more than
- 24:08looking maybe okay on Instagram but keep
- 24:10the puke bucket close by like Dr. Ken
- 24:12Lner used to do in his gym when he'd
- 24:15have those maniacs do sets of 50 in the
- 24:17squat followed by 50 in the deadlift
- 24:19which I highly don't recommend.
- 24:25So summing up, is there a physiological
- 24:28hypertrophy range? Clearly not. Clearly
- 24:31not. But just saying that, just being
- 24:34Mr. Mike Gizer and going reps don't
- 24:36matter or every other popsai article
- 24:38that that repeats the same thing misses
- 24:41the practicalities and the nuances
- 24:45which stating it again. So low reps,
- 24:48time consuming due to the long rest
- 24:49intervals, potentially joint unfriendly
- 24:52and is limited to certain exercises that
- 24:56usually have higher technical demands.
- 24:58The very light load, low load stuff,
- 25:01very painful, takes a long time in my
- 25:03opinion is inefficient because you're
- 25:04having to do 2025 fuckabout reps to get
- 25:07to the five that matter under maximum
- 25:09recruitment. Then in the middle, the
- 25:11practical hypertrophy zone, which splits
- 25:13the middle. Use a slightly lower range
- 25:16for
- 25:18one goal, use slightly higher range for
- 25:20another goal.
- 25:22So, let's finish with some actual, you
- 25:24know, practical recommendations.
- 25:28I think most would agree that that
- 25:30practical hypertrophy zone somewhere
- 25:33between six and 15 or 8 and 15 should
- 25:35make up the grand majority of your
- 25:38training.
- 25:40And to be honest, for most people that
- 25:42could probably make up the entirety of
- 25:43it, right? If you're working in that six
- 25:45to eight range, assuming you're using
- 25:47exercises that lend themselves to it,
- 25:49that you are physically
- 25:51and psychologically built for that. By
- 25:53which I mean, you know, you've got
- 25:55robust enough joints to work in that
- 25:57range for a while, and you like pushing
- 25:58heavy weights, which let's say no is
- 26:02let's 99.9% of males. I didn't really
- 26:05get into gender issues, but my
- 26:07experience is not all women are either
- 26:11built for structurally or want to push,
- 26:15you know, the heaviest weights. Many do.
- 26:17Don't don't mishar me. And obviously, if
- 26:20they want to work in a higher repetition
- 26:21range, that really works so long as the
- 26:24intensity and progression is there. But
- 26:27if someone merely worked in that six to
- 26:2915 range for basically their entire
- 26:31lifting career, you're not going to miss
- 26:33much. So six to eights are going to get
- 26:35maximum strength levels. 15s are going
- 26:38to get you close enough to the the low
- 26:40load stuff,
- 26:42which also isn't to say that being
- 26:45outside of that on occasion will hurt,
- 26:50right? I've described the benefit of,
- 26:53you know, short maximal strength cycles
- 26:55for bodybuilders to push up those neural
- 26:57factors to let you lift heavier weights
- 27:00in a moderate repetition range. But I
- 27:02wouldn't have them done often. Like
- 27:04maybe two three-week blocks a year, like
- 27:07every three primary hypertrophy training
- 27:10blocks. And I'm going to do a video in
- 27:11the future about training cycle length.
- 27:14Maybe with a three-week block at the
- 27:15tail end, or you can think of it as
- 27:17being three weeks leading into the next
- 27:19hypertrophy range, depending on on your
- 27:21perspective. I wouldn't use it often,
- 27:24but I might use it occasionally. If
- 27:27there was a rep range I would tell pe
- 27:29most people stay away from it'd be that
- 27:31lowload [ __ ] I mean it's
- 27:33fascinating that it works but it hurts
- 27:38it. People throw up. It takes too long
- 27:41to get to the good stuff. Like if you've
- 27:42got a joint injury, yes,
- 27:46simply because it will reduce absolute
- 27:47joint loading. Same with blood flow
- 27:49restriction. It absolutely has its use
- 27:51for that. But honestly, who the [ __ ]
- 27:53wants to grind through 25 to 30 to
- 27:57failure in in a leg extension? All
- 27:59right, fine. Maybe if you know, dudes
- 28:00want to just get that massive pump,
- 28:02that's great. But you know what? You can
- 28:04get that with 20s and that can be
- 28:06useful. I said I use it that's depletion
- 28:09workouts and my original ultimate diet,
- 28:11too, and I talk about that in the the
- 28:13new intermittent modified fasting book.
- 28:15But that 6 to 15 spread gets gets most
- 28:18of it. With once again in that lower
- 28:21repetition, 6 to 10, you're going to be
- 28:23looking at generally more compound
- 28:25movements, whether barbell or machines.
- 28:288 to 10, you can get away with some
- 28:29isolation movements. Certainly, if your
- 28:32technique's really good, and having been
- 28:34in the gym for 40 years and 30 years
- 28:37professionally, most y'all's technique
- 28:38is [ __ ] So, there are movements that
- 28:41will probably benefit from being in
- 28:43higher repetition ranges. Like, yeah,
- 28:45you can do a barbell curl for fives. I
- 28:47did it when I was younger, but I think
- 28:48most people, A, it's harder on the
- 28:50elbows, and B, I think most will find
- 28:52that they they're less likely to
- 28:54substitute other muscle groups by
- 28:56working in a slightly higher repetition
- 28:58range. It may be 8 to 10, but even 10 to
- 29:0012, 12, 15. And if you think the pump is
- 29:02better than better than coming, like
- 29:03Arnold said, you may prefer that. the
- 29:07same time. Big compound stuff. Can it be
- 29:09done for high reps? Sure. And here
- 29:12again, there is a gender difference.
- 29:14Like if I give a dude like a set of 15
- 29:17in in a leg movement anywhere close to
- 29:19zero reps reserve, they're going to have
- 29:20to lay down for a few minutes. Whereas
- 29:22you give a woman that same set and
- 29:24she'll be ready to go in 45 seconds.
- 29:26There has to be differences in biology,
- 29:29elasticity, a whole bunch of factors.
- 29:31But the these are the important things
- 29:33that that gets left out of the rep count
- 29:36doesn't matter. Right? So again,
- 29:38practically six to 15 will get it done
- 29:40for most people
- 29:42with exercise selection playing a
- 29:44secondary role.
- 29:46Isolations tend to work better in higher
- 29:49repetition ranges. Compounds tend to
- 29:52work better in lower repetition ranges
- 29:54with some overlap. between 8 and 12, the
- 29:56hypertrophy zone, it's kind of a wash,
- 29:59but six to eights, most people aren't
- 30:02probably going to do, you know, lateral
- 30:04raise as well in that unless your
- 30:06technique is perfect and y'alls ain't 12
- 30:09to 15s.
- 30:11If you do a set of hack squats in that
- 30:13range, you're going to have to go lay
- 30:14down for a few minutes if it's anywhere
- 30:15close to intense. There may be some
- 30:18gender differences. There may be gold
- 30:21differences, right? Like again, I don't
- 30:22I don't I suspect the the typical female
- 30:26who's a competitor who's working, you
- 30:28know, looking at at one of the non
- 30:30bodybuilding or physique divisions when
- 30:32you get a bikini fit model, fit wellness
- 30:35or one of the other 137 divisions,
- 30:37probably not be doing lots of heavy six
- 30:39to eights and probably in the 125 rep
- 30:42range because it suits them
- 30:44physiologically, possibly anat
- 30:46anatomically. Guys love to go heavy.
- 30:49Joints don't always handle that.
- 30:52Um, I know this is disorganized because
- 30:54I don't script it, guys, because I can't
- 30:56be bothered.
- 30:58One thing that I've written about
- 31:00speculatively, I should probably put
- 31:01something about this formally. Like, if
- 31:03you're coming out of heavy stuff and
- 31:05your joints a little beaten up, doing a
- 31:07couple weeks in that 15 to 20 rep range,
- 31:10moving a lot of blood, things of that
- 31:12nature can be really good for your
- 31:13joints, right? There is no metabolite
- 31:16growth cycle. It's just another way to
- 31:19high tension. But like I could probably
- 31:21come up with a cycle that's, you know,
- 31:23couple weeks of high reps, give your
- 31:25joints a break, move a lot of blood,
- 31:28maybe get a little growth from
- 31:30metabolites, probably not fiber type
- 31:32specific. Would I go to 30? Abso
- 31:34fuckingutely not for reasons already
- 31:37explicated. Yes, explicated. The
- 31:40majority then I would do several blocks
- 31:42in a six to 15 rep range. A mix is
- 31:45always nice. By which I mean the
- 31:47combination of six to eight for heavier
- 31:50compounds and 10 to 12 or 12 to 15s in
- 31:52isolations is a time-tested
- 31:55way of training. So
- 31:58success may not always leave clues, but
- 32:01sometimes it does. And then if it fit
- 32:05someone's goals, I might finish with a
- 32:06three-week block of maximal strength
- 32:09training.
- 32:13So there you go. Now you know is there a
- 32:17hypertrophy zone? Not in the strictest
- 32:20physiological sense. Is there a
- 32:22practical hypertrophy zone? Obviously in
- 32:24my opinion that is the case.
- 32:27And that we're going to call it six to
- 32:2915 range will probably be the most
- 32:33beneficial from the grand majority of
- 32:35trainees under the grand majority of
- 32:37conditions for the grand majority of
- 32:39their training with context specific
- 32:42reasons to include either five reps and
- 32:46less short maximum strength cycle maybe
- 32:49up to 20 because nobody's doing three
- 32:52sets of 25 to 30 leg extensions to zero
- 32:55reps in reserve consistently.
- 32:58See you next time.
- 33:02Okay, so since the date has passed, my
- 33:06twomonth run long run 20% off discount
- 33:10sale is now unofficially over. However,
- 33:13that means you can go back to as always
- 33:16using the coupon code Mike has no tan,
- 33:18which maybe I should change to Mike has
- 33:20a bubble gut despite that plastic
- 33:22surgery. that will give you 10% off on
- 33:25every book in my store consultations.
- 33:28It will stack with the multibook
- 33:30discount. It will not stack with any
- 33:32other coupons, but I don't have any
- 33:34other coupons. Once again, coupon code
- 33:37Mike has no tan. 10% off anything in my

- 33:50There you go. By which I mean the

- 33:54compounds and 10 to 12 or 12 to 15s in
- 33:56isolations is a time-tested
