It’s Weird, But Tendon Training Makes You Stronger Than Lifting — Transcript

Full transcript

1. 0:00One tissue in your body carries every
2. 0:02pound of strength you own, and almost
3. 0:04nobody trains it directly. Muscle gets
4. 0:06the credit, but muscle doesn't touch the
5. 0:09bone. Tendons do, and they set the
6. 0:11ceiling on how much of your strength
7. 0:13ever reaches anything you pick up.
8. 0:15That's why a person can train for years
9. 0:17and still feel fragile. There are five
10. 0:19movements that load that tissue
11. 0:21directly, and none of them need a gym, a
12. 0:23barbell, or a machine. Which brings us
13. 0:26to the first movement, the dead hang.
14. 0:28And it's exactly what it sounds like.
15. 0:30You grab a bar with both hands about
16. 0:32shoulder width apart, let your arms go
17. 0:34straight, relax your shoulders down away
18. 0:36from your ears, and pick up your feet.
19. 0:38Then you just hang there. Nothing about
20. 0:40this looks like training, and that's the
21. 0:42whole point. The muscle isn't doing much
22. 0:44work at all, but the connective tissue
23. 0:46through your forearms, elbows, and
24. 0:48shoulders is holding every ounce of your
25. 0:50weight in one steady pull. A muscle
26. 0:53can't move a bone on its own, and the
27. 0:54reason goes back to the way your body is
28. 0:56built, because muscle tissue never
29. 0:58attaches to bone directly. Instead, it
30. 1:01hands its force off to a tendon, and the
31. 1:03tendon is the part that actually pulls
32. 1:05on the bone. The muscle generates, and
33. 1:07the tendon transmits. Here's why the two
34. 1:10tissues can't be trained the same way.
35. 1:12Muscle protein turns over in days, so a
36. 1:14hard workout shows results fast, while
37. 1:17tendon collagen reorganizes on a much
38. 1:19slower clock. That gap shows up when
39. 1:21someone adds muscle for a full year and
40. 1:24still winces every time they reach
41. 1:25overhead for a jar on the top shelf. The
42. 1:28payoff for that patience is a stiffer
43. 1:29tendon. And a stiffer tendon wastes less
44. 1:32of what your muscle produces,
45. 1:33>> [music]
46. 1:33>> so more of the pull actually reaches the
47. 1:35bone. That's the part lifting alone
48. 1:37tends to miss. So hang for 20 to 40
49. 1:40seconds, rest for about a minute, and
50. 1:42then run [music] two more sets, which
51. 1:44adds up to under 5 minutes of work. If
52. 1:4620 seconds already feels easy, put on a
53. 1:49backpack or tuck a dumbbell between your
54. 1:51feet. When it feels heavy, start at 10
55. 1:53seconds and build from there. Now for
56. 1:56the number that makes all of this worth
57. 1:58your time. Researchers followed almost
58. 2:00140,000 adults in 17 countries, and the
59. 2:03one measurement they took came down to
60. 2:05how hard a person could squeeze with one
61. 2:07hand. Every 5 kilos lost from that
62. 2:09squeeze came with a 16% higher risk of
63. 2:12dying during the study. Grip strength
64. 2:14beat blood pressure as a predictor of
65. 2:15death. The honest reading is that grip
66. 2:17strength is a signal and not a verdict.
67. 2:20The people who ran that study pointed
68. 2:22out plainly that a lot more work is
69. 2:23needed before anyone can claim that
70. 2:25training strength extends your life.
71. 2:27What the number does tell you is that
72. 2:29the tissue in your hands and forearms
73. 2:31has been talking about your whole body
74. 2:33the entire time and nobody has been
75. 2:36listening. The dead hang covers the
76. 2:38pulling half of your upper body. There's
77. 2:40one tendon in your lower body that
78. 2:41carries more load than any other tendon,
79. 2:44and it's the one that gives out most as
80. 2:46people age. That tendon gets its turn in
81. 2:48a few minutes, but first there's a
82. 2:50movement you've almost certainly done
83. 2:52and never once used this way. You've
84. 2:54probably met the wall sitting in a gym
85. 2:56class and filed it away as a leg burner.
86. 2:59That's a shame because a wall sit is one
87. 3:01of the simplest ways to put slow,
88. 3:03steady, uninterrupted tension through
89. 3:05the tendons that wrap around your knee.
90. 3:07The setup barely changes from the
91. 3:09version you remember. Back flat against
92. 3:11the wall, feet roughly shoulder width
93. 3:13apart, slide down until the thighs are
94. 3:16level with the floor. The tendon reason
95. 3:18has to do with angles. Tendon tissue
96. 3:20responds to sustained load at a fixed
97. 3:22joint angle, and holding one position
98. 3:24for 40 seconds gives the tissue an
99. 3:26unbroken signal that a fast rep never
100. 3:28delivers. The quadriceps [music] tendon
101. 3:30above your kneecap and the patellar
102. 3:32tendon below it are both under load the
103. 3:35entire time you sit there. Depth changes
104. 3:37the load more than people expect. A
105. 3:39shallow sit at around 110° of knee bend
106. 3:43loads the tissue differently than a deep
107. 3:44sit at 90° does. Rotating through a few
108. 3:47depths across your sets reaches more of
109. 3:50the tendon than parking at one angle
110. 3:52ever will, which is why shallow and deep
111. 3:54both deserve a turn. The first stretch
112. 3:56of a wall sit feels like muscle work.
113. 3:59Right around the 30-second mark, the
114. 4:00burn settles and the load seems to sink
115. 4:02deeper into the joint, and that's about
116. 4:04when the connective tissue takes over
117. 4:06the holding. Hold for 40 to 60 seconds,
118. 4:09run three sets, and take about a minute
119. 4:11between them. Change your depth between
120. 4:14sets. So, one set sits at 90°, the next
121. 4:17at 110°, and the last one a bit
122. 4:20shallower. If your knees feel pinched
123. 4:22rather than loaded, raise the depth and
124. 4:25back off. The wall sit has a second
125. 4:27payoff that has nothing to do with
126. 4:29knees.
127. 4:30A 2024 review in the journal Sports
128. 4:33Medicine looked at isometric training,
129. 4:35which is holding a contraction without
130. 4:37moving. It found that holding still
131. 4:39lowers resting blood pressure more than
132. 4:41standard exercise guidance manages, with
133. 4:44drops near 10 points of systolic and
134. 4:46seven of diastolic. The wall squat
135. 4:48needed no equipment at all, and sessions
136. 4:51ran 11 to 20 minutes. That evidence
137. 4:53covers isometric training in general
138. 4:55rather than this exact hold, [music]
139. 4:57so treat the numbers as a reason for
140. 4:58hope. The wall sit handles the tendons
141. 5:01around your knee. Now, the lower body
142. 5:03still has one more piece, and it happens
143. 5:05to be the tendon that causes the most
144. 5:07trouble for people as they get older.
145. 5:09This is the kind of training the full
146. 5:11program is built around. The goal ends
147. 5:13up being stable joints, tendons that can
148. 5:15take a real load, and strength that
149. 5:17shows up in daily life rather than only
150. 5:20in a gym. No equipment, no heavy
151. 5:22lifting, and nothing that punishes a
152. 5:24sore knee. If you'd rather have the
153. 5:26whole thing laid out than piece it
154. 5:27together yourself, scan the QR code on
155. 5:30screen or use the first link in the
156. 5:32description. That's the tendon from a
157. 5:34few minutes ago, and it gets its own
158. 5:36movement for a reason. The Achilles is
159. 5:38the strongest tendon in your body. It
160. 5:40runs down the back of your calf,
161. 5:42attaches to your heel, and takes the
162. 5:44full load of every step, jump, and
163. 5:46landing you've ever taken. So, the
164. 5:48strongest tendon you own is also one of
165. 5:50the most likely to give out, which
166. 5:51sounds backwards until you remember how
167. 5:53little direct work it usually gets. The
168. 5:56heel drop works because of the way down,
169. 5:58not the way up. When you lower a heel
170. 6:00slowly, the calf muscle lengthens while
171. 6:02it's still producing force, and that
172. 6:05pairing loads tendon tissue harder than
173. 6:07any other moment in a repetition. That's
174. 6:09the eccentric, and it's why the heel
175. 6:11drop shows up in the tendon research
176. 6:13more than anything else. Stand with the
177. 6:16balls of your feet on a step and your
178. 6:17heels hanging off the edge. Rise up on
179. 6:20both feet, lift one foot off the step,
180. 6:22and then lower the working heel all the
181. 6:24way down over 3 to 5 slow seconds. Then
182. 6:27put both feet back down and start over.
183. 6:29The way up is just how you get back to
184. 6:31the start. This is the movement Swedish
185. 6:33researcher Håkan Alfredson built a
186. 6:35protocol around, and it's still the most
187. 6:37evidence treatment for mid-portion
188. 6:39Achilles problems. The original protocol
189. 6:42is a demanding one. His patients did
190. 6:44three sets of 15 reps twice a day for 12
191. 6:47weeks. Worked through once with the knee
192. 6:49straight and again with the knee bent.
193. 6:51That's a rehab protocol for people who
194. 6:53already have an irritated Achilles, and
195. 6:56it's meant to be done with some
196. 6:57discomfort, so it's not a starting
197. 6:59point. If your tendon is healthy, the
198. 7:01dose is smaller. Catching a problem
199. 7:03early is the whole reason to train this
200. 7:05way. An irritated tendon takes far
201. 7:07longer to settle than a sore muscle
202. 7:09does, and the long route back is the one
203. 7:11Alfredson mapped out over 12 weeks of
204. 7:13daily work. Do three sets of eight to 12
205. 7:16reps per leg, two or three times a week.
206. 7:18Keep the lowering phase at a full 4
207. 7:20seconds, because speed is the thing that
208. 7:23turns a tendon exercise into a plain old
209. 7:25bounce off the step. Add load, not reps,
210. 7:28once eight reps feel dull. The follow-up
211. 7:30data is what makes this worth the
212. 7:32patience. Researchers tracked 46
213. 7:35patients 5 years after a 12-week heel
214. 7:37drop program, and their Achilles scores
215. 7:40climbed from around 49 to almost 84. Out
216. 7:44of 100 points, that's a jump of 35.
217. 7:47About 40% of them were completely free
218. 7:49of pain at the 5-year mark. Nearly half
219. 7:52of those patients still ended up trying
220. 7:54other treatments. So, this is a strong
221. 7:56option rather than a miracle. The heel
222. 7:58drop handles the tendon that fails most
223. 8:01often, and it does all of that work
224. 8:03without ever adding a single pound of
225. 8:05external load. Next up is the upper body
226. 8:07push chain, and it deserves more thought
227. 8:09than it usually gets. Your upper body
228. 8:11has a push chain, and it runs from your
229. 8:13wrists through your elbows and into your
230. 8:15shoulders. Every link in that chain has
231. 8:18a tendon in the middle of it. Those
232. 8:20tendons are usually the first thing to
233. 8:21complain after a long day spent gripping
234. 8:23tools, holding a steering wheel, and
235. 8:26typing away at a desk. A push-up hold
236. 8:28puts all three of those links under
237. 8:30tension at once. Get into a push-up
238. 8:32position and lower yourself until your
239. 8:34chest is about an inch from the floor,
240. 8:36then stop moving and hold that exact
241. 8:38position. Your elbows stay bent. Your
242. 8:41body holds one long line from head to
243. 8:43heel, and nothing moves except the small
244. 8:45corrections that keep you steady. The
245. 8:47difference between a hold that works and
246. 8:49a hold that wastes your time comes down
247. 8:52to intention. A plank gets survived, and
248. 8:54a tendon load gets pushed. So, press the
249. 8:57floor away [music] from you the whole
250. 8:58time instead of hanging out in the
251. 8:59position. That single cue changes what
252. 9:02the tissue is actually doing. Forearm
253. 9:04and elbow tendons are a common trouble
254. 9:06spot for anyone who uses their hands all
255. 9:09day. And the pull side of that problem
256. 9:11gets plenty of attention. The push side
257. 9:13gets almost none. Hold for 15 to 30
258. 9:16seconds and run three sets with about 45
259. 9:19seconds of rest between them, which
260. 9:21keeps the whole thing under 3 minutes of
261. 9:23work. If the full position is too much,
262. 9:25drop to your knees. Once 30 seconds
263. 9:28feels solid, lift one foot clear of the
264. 9:30floor for a few seconds at a time. The
265. 9:32mistake is chasing the shake. Tendons
266. 9:34don't respond to burning the way muscle
267. 9:36does, and a set that leaves you
268. 9:38trembling teaches you almost nothing
269. 9:40about how much load the tissue can
270. 9:41actually manage. Stop the [music] set
271. 9:44while the position still feels
272. 9:45controlled. That's four movements
273. 9:47covered with one left. The final one is
274. 9:49the quietest of the bunch, and it's also
275. 9:51the one people skip most, which is
276. 9:53exactly why it deserves a spot on the
277. 9:55list. Lie on your back with your knees
278. 9:57bent and your feet flat on the floor,
279. 10:00about hip-width apart. Press through
280. 10:02your heels and lift your hips until your
281. 10:04body forms one long straight line from
282. 10:06your shoulders down to your knees, and
283. 10:08hold it there. Don't let the hips drop.
284. 10:10This one loads the tendons behind your
285. 10:12hips and behind your knees, where the
286. 10:14glutes and hamstrings anchor to bone.
287. 10:16Joint stress stays low while the tissue
288. 10:19itself sits under real tension, and that
289. 10:21balance is exactly what makes a movement
290. 10:24useful for tendons rather than just for
291. 10:26muscle. It's a load you can feel without
292. 10:28a joint you have to worry about. The
293. 10:30back half of your body is what keeps you
294. 10:32upright, and it's the first thing that
295. 10:33goes quiet after sedentary years behind
296. 10:36a desk. It goes quiet without much
297. 10:38warning. Getting out of a chair,
298. 10:40climbing stairs, and catching yourself
299. 10:42when you trip all run through that same
300. 10:44chain. This is where aging starts to
301. 10:46matter more. A 2023 paper in the
302. 10:49International Journal of Molecular
303. 10:50Sciences laid out what happens to
304. 10:53tendons over time, and the list turns
305. 10:55out to be a specific one. It includes
306. 10:57fewer tendon stem cells, collagen
307. 10:59bundles that come apart and lose their
308. 11:01organization, and extra cross-links that
309. 11:03make the tissue stiffer. That same paper
310. 11:05noted that tendon problems affect
311. 11:07roughly a quarter of adults. Tendons
312. 11:10also heal slowly because the tissue
313. 11:12carries very little blood supply
314. 11:14compared with muscle, which is a big
315. 11:16part of the reason a tendon injury can
316. 11:19nag for months. Hold for 30 to 60
317. 11:21seconds and do three sets. Once that
318. 11:24feels easy, extend one leg and hold with
319. 11:26the other, which doubles the load on the
320. 11:28working side without adding any weight
321. 11:30to the movement at all. It's the
322. 11:32movement people skip because it feels
323. 11:34too easy, and feeling easy isn't the
324. 11:36same thing as being unloaded. The other
325. 11:38reason to keep it as simple, the two-leg
326. 11:40version asks almost nothing of you, and
327. 11:42the full set fits into a morning in
328. 11:44under 4 minutes, so the low cost is what
329. 11:46makes it stick. Five movements, five
330. 11:49different chains, and not one of them
331. 11:51needed a barbell or a machine. Dead
332. 11:53hang, wall sit, heel drop, push-up hold,
333. 11:56and glute bridge. Every one of those run
334. 11:59is a long hold or a slow lower instead
335. 12:01of a fast rep. That's the entire
336. 12:03difference between training a muscle and
337. 12:05training the cable that carries it. The
338. 12:07tissue doing the carrying is what sets
339. 12:09your ceiling. Strength that lasts was
340. 12:11never about how hard a muscle can pull,
341. 12:14because a muscle can only hand off as
342. 12:16much as the tendon is able to carry.
343. 12:18Your ceiling was never effort or
344. 12:19willpower. It was the tissue nobody
345. 12:21trains. 5 minutes, three times a week,
346. 12:25and the cable starts catching up. So,
347. 12:27subscribe if you want the next one.
