Your Creaky Joints? It's Your Tendons, Not Bones
48sChallenges the common belief that joint popping is normal, hooking viewers with a science-backed explanation.
βΆ Play ClipSqueaky-creaky joints are often a sign of tendon weakness, not just normal training wear-and-tear. This video explains that tendons require different training than muscles to stay healthy and prevent pain, especially as you age.
Squeaky-creaky joints are not a normal part of training; the problem is likely your tendons, not muscles or bones.
Tendons act like cables to move your body and protect muscles by stretching quickly during impact, like landing from a jump.
Tendons and muscles respond differently to loads; tendons need specific training to strengthen, as they don't like what muscles like.
If muscles outgrow tendons, it creates a strength gap, leading to painβ70% of sports injuries involve tendons or their associated muscles.
Steroid use accelerates muscle growth faster than tendon adaptation, increasing tendon tear riskβseen in 1990s baseball players.
Clicking joints, especially with pain, can indicate a swollen tendon; clicking alone may be normal, but pain signals weakness.
Rest is ineffective for tendons; they need load to heal. Complete rest weakens healthy tendon parts and leaves damaged areas unrepaired.
Suddenly increasing activity volume or intensity by more than ~30% risks tendon injury. Slow progression (adding 1-2 sets per week) is safer.
Momentum (bouncing weights) introduces harmful loads to tendons. Controlled reps at bottom positions are better for tendon health and muscle growth.
Isometric exercises (holding a contraction) maximize tendon creep and signal healing to scarred areas within 2 weeks, making them a top rehab method.
Choose isometric holds in the same movement that bothers you (e.g., bench press hold for shoulder pain). Hold for 30 seconds, 3 sets, twice daily.
Do 3 sets of isometric exercises twice daily for 1-2 weeks; then 3-4 times per week for 4-8 weeks to prevent pain from returning.
Spend 5-10 minutes after workouts or dedicate one day per week to tendon exercises for permanent health and injury prevention.
Tendon injuries are common but fixable with specific isometric exercises and careful load management. Consistent rehab (30-second holds, 3 sets twice daily for 1-2 weeks, then 3-4 times weekly for 4-8 weeks) can permanently resolve pain and strengthen tendons.
"The title accurately promises fixes for knees, elbows, and shoulders, and the video delivers specific isometric exercises for each joint, matching the claim closely."
What are the two biggest mistakes that damage tendons?
Poor load management (increasing volume or intensity by more than ~30%) and using momentum (bouncing weights).
4:11
Why is complete rest ineffective for tendon injuries?
Rest weakens healthy tendon parts while leaving damaged areas unrepaired, so pain returns when activity resumes.
3:07
What type of exercise is proven to heal and strengthen tendons?
Isometric exercises (holding a contraction) for 30 seconds per hold.
6:29
How quickly can tendon pain reduce with isometric exercises?
Within 1-2 weeks of doing 3 sets twice daily.
9:30
How often should isometric exercises be done for long-term tendon health?
3-4 times per week for 4-8 weeks after initial healing.
9:48
What percentage increase in volume or intensity puts tendons at risk of injury?
More than about 20-30%.
4:56
What is a safe way to increase load for tendons?
Add only 1-2 sets per week or increase load by ~30% (e.g., from 100 lb to 130 lb).
5:11
What is the 'strength gap' that causes tendon pain?
When muscles grow faster than tendons, creating a strength disparity that leads to injury.
1:36
What hormone-related behavior increases tendon tear risk?
Using anabolic steroids, which cause muscles to outgrow tendon strength.
1:57
How do tendons respond to momentum during exercise?
Momentum introduces loads that are hardest on connective tissues, potentially damaging tendons.
5:32

6:29[00:02] Squeaky-creaky joints are not just a
[00:04] normal part of training. And if it keeps
[00:06] coming back, problem isn't your muscles
[00:07] or bones, it's your tendons.
[00:09] >> It's the number one thing that causes
[00:11] people pain.
[00:12] >> Today, I'll show you the two biggest
[00:13] mistakes damaging your tendons and the
[00:16] exact [music]
[00:17] exercises proven to rebuild stronger
[00:19] ones in as little as 30 days. Think of
[00:22] tendons as the cables that make your
[00:23] body move. Whether it's lifting your
[00:25] forearm up during a curl, pulling your
[00:27] arm across your body during a bench
[00:28] press, or swinging your elbow when you
[00:30] hit a tennis ball. But movement isn't
[00:32] their only job.
[00:33] >> Imagine that you jump down off of a
[00:37] couple of stairs and you landed on both
[00:38] feet. Well, when you land on the ground,
[00:40] you don't want your muscle to take on
[00:42] all of the load.
[00:43] >> That's Coach Q Wiley, a physiotherapist
[00:46] who spent years studying tendons and
[00:48] applying this research with professional
[00:50] athletes.
[00:51] >> So, tendon can be very protective of
[00:53] muscle in that it can basically stretch
[00:56] out quite a bit in a very fast, short
[00:58] period of time that allows the muscle to
[01:00] not have to extend as quickly.
[01:02] >> Which just means your tendons need to be
[01:04] absurdly strong. And even though lifting
[01:06] weights is great for building your
[01:07] muscles,
[01:08] >> [music]
[01:08] >> your tendons need a different type of
[01:10] training.
[01:11] >> The biggest thing that we're discovering
[01:12] now and is that tendons don't like what
[01:14] muscle likes to get stronger.
[01:16] >> That's Dr. Keith Baar, a professor at UC
[01:18] Davis whose lab has produced some of the
[01:21] world's most cited research [music] on
[01:22] tendon healing and strength.
[01:24] >> And so, there's a big difference in the
[01:26] types of loads that we do to optimize
[01:28] tendon
[01:30] versus when we're trying to target our
[01:31] exercise for muscles or our heart.
[01:34] >> So, if all your training builds up your
[01:36] muscles faster than your tendons, it
[01:38] creates a big gap in strength, which
[01:40] explains why
[01:41] >> it's the number one thing that causes
[01:43] people pain. So, I do a lot of work with
[01:45] professional sports team because 70% of
[01:48] their injuries are related to the tendon
[01:50] and it either the tendon or the muscle
[01:52] that was associated with it not being
[01:54] perfectly aligned.
[01:55] >> This is actually why guys who hop on
[01:57] steroids are usually more likely to get
[01:59] tendon injuries. Their muscles outgrow
[02:01] the strength of their tendons. And we
[02:03] see the same trend in professional
[02:05] sports. 1990s
[02:07] baseball where everybody was injecting
[02:09] himself with anabolic steroids,
[02:11] they would get big muscles and then they
[02:13] would tear the the tendon. Their
[02:15] performance would go up and then bang.
[02:17] And you know, statisticians can go back
[02:19] and and determine who is taking steroids
[02:22] based on their stats because it's that
[02:23] predictable. But you don't need to be on
[02:25] the juice for this to happen. And even
[02:27] if you're not in pain, there are warning
[02:28] signs that some of your tendons are just
[02:30] not as strong as they should be.
[02:33] >> Oh my god, that's loud.
[02:35] >> Hear that? When a tendon is experiencing
[02:38] any kind of sensitive thing, it it will
[02:41] get a little bit fatter. You know, it's
[02:43] a chubby tendon, if you will. And so now
[02:45] in the shoulder, particularly, you're
[02:47] asking that tendon to move and slide
[02:49] through very, very narrow joint spaces.
[02:51] And so just a little bit of a fatter
[02:53] tendon, now you may feel that tendon as
[02:56] it pops and rolls.
[02:57] >> Now, clicking alone doesn't always mean
[02:59] your tendon is weak or damaged. But when
[03:02] it starts coming with pain, that's a
[03:03] different story. And one of the worst
[03:05] things you can do when that happens
[03:07] >> [music]
[03:07] >> is rest. The doctor says, "Well, just
[03:09] rest it."
[03:10] But a tendon isn't a tendon without
[03:12] load.
[03:13] So if you're just resting it, it's never
[03:16] going to fix itself. Unlike most
[03:17] injuries, tendons don't respond well to
[03:19] complete rest. The pain might
[03:21] temporarily go away because nothing's
[03:22] stressing it, but the actual problem
[03:24] isn't being fixed. In fact, the healthy
[03:27] parts of the tendons start actually
[03:28] getting weaker while the damaged part
[03:30] never properly rebuilds. As a result,
[03:33] >> as soon as you start doing anything
[03:34] again, the pain is going to come back
[03:36] cuz you didn't actually fix the problem.
[03:37] And this only gets worse as you age.
[03:39] When we're young and healthy and we're
[03:40] doing all of these activities, those
[03:42] little injuries never go away unless we
[03:45] actually fix them. That's why a lot of
[03:46] people who are super active and are
[03:48] training really hard, And they'll get
[03:50] into their 40s and they'll have a lot of
[03:52] kind of muscular musculoskeletal pain.
[03:55] >> Okay, so rest doesn't work. But before I
[03:57] show you what does, the exact exercises
[03:59] for each joint that can get rid of pain
[04:01] instantly and rebuild your stronger
[04:03] tendons in as little as 30 days,
[04:05] >> [music]
[04:05] >> you need to understand the two biggest
[04:08] mistakes causing your tendon problems in
[04:10] the first place. The first and most
[04:11] common one is poor load management.
[04:14] Think back to a time when you suddenly
[04:15] increase your activity, whether it's
[04:17] more bench pressing, running, or new
[04:19] sport.
[04:19] >> It feels fine at first until after a few
[04:21] weeks
[04:22] >> something gives.
[04:23] >> It's less about being an overuse-related
[04:26] injury, it's more of an more is just
[04:28] more.
[04:31] We can adapt to more, it just takes a
[04:32] long time. Tendons
[04:34] take a little bit longer to adapt than
[04:36] muscle.
[04:37] >> I actually experienced this myself. I
[04:39] ran a 60-day experiment where I trained
[04:41] one half of my body with really heavy
[04:43] weights for low reps, and the other half
[04:46] with light weight for high reps. By the
[04:47] end of it, I got tendinitis on both my
[04:50] elbow and knee on my heavy side. Now,
[04:51] it's not because heavy weight is bad,
[04:53] but just because my body wasn't used to
[04:55] that type of training.
[04:56] >> If you're increasing volumes or
[04:57] intensity by more than probably about
[05:00] 30% that you're potentially running the
[05:02] risk
[05:03] >> of injury.
[05:03] >> So, if you normally do four sets of
[05:05] bench per week and hop on a new program
[05:06] that has you doing 10, that's a recipe
[05:09] for injury. A 30% jump is at most adding
[05:11] one to two sets per week. And the same
[05:13] goes with load. If you're coming back
[05:15] from time off and 100 lb feels easy,
[05:17] don't jump straight to 150 the next
[05:19] week. Go closer to 130 and slowly build
[05:22] from there. And you can also apply this
[05:23] concept to any exercise or sport you do
[05:26] outside of the gym, too. But there is
[05:27] another more subtle mistake that almost
[05:30] everyone does that damages their
[05:31] tendons.
[05:32] >> When we're lifting a lot, what happens,
[05:34] especially as we're trying to up our
[05:36] weights, is that we have a tendency to
[05:38] use more momentum.
[05:39] >> Momentum is what you use whenever you
[05:41] bounce the weight off your chest when
[05:42] pressing, bounce at the bottom of a
[05:44] squat, or even hit a tennis ball or
[05:46] swing a golf club. That's the stimulus
[05:48] that's going to be detrimental to our
[05:50] connective tissues. We're doing the
[05:51] things that are actually introducing the
[05:54] type of load that is hardest on our
[05:57] tendons.
[05:57] >> Now, even though Olympic weightlifters
[05:59] use momentum all the time in their
[06:01] lifts, their tendons have adapted to it
[06:03] over time. Yours hasn't. So, as a
[06:05] general rule of thumb in the gym,
[06:07] >> [music]
[06:07] >> if you don't have specific power or
[06:09] strength goals, control the bottom of
[06:11] the rep. It'll not only be easier on
[06:12] your tendons, research also suggests
[06:15] it'll grow your muscles faster, too.
[06:17] But, even if you manage your training
[06:19] perfectly, tendon injuries still happen.
[06:22] And luckily, there is one type of
[06:24] exercise proven to be one of the best
[06:27] ways to heal and build stronger tendons.
[06:29] >> What our work has shown us is that when
[06:31] we do isometrics, we maximize the creep
[06:35] in the tendon,
[06:36] and we get equal signal for that load
[06:39] through the whole tendon, including the
[06:41] scarred area. By 2 weeks, almost
[06:43] everybody is is like, "Oh, yeah. I I
[06:45] don't I can do pretty much everything
[06:47] again."
[06:47] >> An isometric is any exercise where
[06:49] you're contracting a muscle without
[06:51] moving it, like flexing your bicep with
[06:52] your elbow stuck in 90Β°.
[06:54] >> So, the reason that we use isometrics is
[06:58] because if I pull and hold, what's going
[06:59] to happen is that's going to cause creep
[07:01] to the healthy strong parts of the
[07:03] tendon.
[07:04] And as they lengthen, the next strongest
[07:06] part gets load. Then the next strongest,
[07:09] then the weakest part will get it. So,
[07:11] if we hold it about 30 seconds, now the
[07:13] whole tendon gets a signal. Now, we're
[07:15] going to get collagen synthesis, it's
[07:17] going to happen in a line fashion, and
[07:19] we're going to make that tissue
[07:20] stronger.
[07:21] >> As for what isometric exercises are
[07:23] best,
[07:24] >> whatever motion doesn't feel good,
[07:26] you're trying to find a way that you can
[07:28] load that motion very hard, um, or hold
[07:32] a position. So, for example, if I had a
[07:33] problem bench pressing, [music] I'm
[07:35] going to probably use something pretty
[07:37] similar to a bench press, and just do an
[07:39] iso hold there, because that's the
[07:41] motion that's most sensitive, meaning
[07:43] that I know that that's probably the
[07:44] motion that that tendon is getting the
[07:46] most load. Let me show you what this
[07:48] looks like for each joint using
[07:50] exercises we actually just added to our
[07:52] fitness app. Starting with the shoulder.
[07:54] If chest pressing is what bothers you,
[07:56] set up a bench press, Smith machine, or
[07:58] chest press machine with enough weight
[08:00] so that you can push hard against it
[08:01] without the weight moving.
[08:05] Another option too is just using a
[08:06] lighter weight and holding it halfway
[08:08] through the rep. And if you're training
[08:10] at home, you can do the same thing with
[08:12] a push-up hold or by pushing hard
[08:13] against the wall. But pick one of these
[08:15] variations, hold the position for at
[08:17] least 30 seconds, and repeat that
[08:19] [music] for a total of three sets.
[08:21] Whereas if your shoulder mainly hurts
[08:23] during overhead presses, try these
[08:25] instead.
[08:26] And if it hurts during lateral raise
[08:28] movements, then try these. And before we
[08:30] move to the elbow, just keep in mind
[08:31] that while you should feel temporary
[08:33] pain relief right after you do these
[08:35] exercises, you might actually feel some
[08:37] pain as you're doing them. And that's
[08:39] perfectly fine, as long as the pain is
[08:41] not more than a three or four out of 10,
[08:43] and as long as it doesn't feel worse the
[08:45] next day. If it does, that's a sign you
[08:47] got to ease back by using less weight or
[08:49] just not pushing as hard. Now, as for
[08:51] your elbows, if it's mainly your biceps
[08:53] that hurt, pick whatever type of curl
[08:55] bothers you the most and hold the middle
[08:58] position of it with lighter weight. And
[08:59] do the same if it hurts during
[09:01] pull-downs or chin-ups. Whereas for
[09:02] triceps, [music] do these if it hurts
[09:04] during push-downs, and these if it hurts
[09:06] during overhead extensions. As for your
[09:08] knees, knee extension machine is
[09:10] probably just the most simple, uh most
[09:13] accessible. If you didn't have a
[09:14] machine, getting your toes to be the
[09:17] only thing that are on the floor and
[09:18] your back and your bum are now up
[09:20] against the wall and simply sliding down
[09:22] the wall with your back and and letting
[09:24] the knees come forward is also going to
[09:25] recreate a very similar knee extension
[09:28] type thing. So here is the full plan to
[09:30] completely heal and rebuild your tendons
[09:33] as fast as possible. First, pick one
[09:35] exercise based on what joint is
[09:37] bothering you and do three sets of it
[09:39] twice a day, [music] once in the morning
[09:40] and once in the evening. Your pain can
[09:42] go away in as quick as a week or two
[09:44] just from that. But to then fix the
[09:46] issue for good, Keith recommends [music]
[09:48] continuing to do your exercises three to
[09:50] four times a week for at least four to
[09:52] eight weeks.
[09:53] >> If they feel like, "Oh, yeah. Hey, it's
[09:55] better." and then they stop doing it,
[09:57] it's just going to come back. So, that's
[09:58] why the ones who really get rid of the
[10:00] pain permanently are the ones who can
[10:02] say, "This is something I want to keep
[10:03] going with." But again,
[10:05] >> don't stop there. If you want to keep
[10:06] your tendons healthy for good and
[10:07] prevent future injuries, you can spend 5
[10:10] to 10 minutes after your workouts to do
[10:12] these exercises or just allocate one day
[10:14] per week. But if you want a step-by-step
[10:16] plan that takes care of all that
[10:18] guesswork for you, we've actually added
[10:20] these tendon rehab exercises directly
[10:22] into our app along with joint-friendly
[10:24] exercise [music] alternatives based on
[10:26] the specific area that's bothering you.
[10:28] That way, you can continue training and
[10:30] continue building muscle while
[10:32] rebuilding your tendons at the same
[10:33] time. Now, the app also coaches you on
[10:35] your diet and you can try 2 weeks
[10:37] completely free by scanning this QR code
[10:40] or heading to buildwithscience.com. Give
