The video outlines several key insights regarding tendon health and recovery steps through isometric training. Here are the details:
Key Insights on Tendon Health:
The Strength Gap: Dr. Keith Baar explains that tendons and muscles adapt to different loads. A strength gap occurs if muscles grow stronger or faster than the associated tendons, which is a primary cause of pain and injury (1: 11 - 2: 05.
The Failure of Rest: The video states that complete rest is ineffective for tendon recovery because tendons require load to heal. Rest may temporarily mask pain, but it causes healthy tissue to weaken while the damaged area fails to rebuild correctly (3: 06 - 4: 04.
Load Management Mistake: Injury often stems from being underprepared for a sudden increase in work. Increasing volume or intensity by more than 30% in one go is a common trigger for tendon issues (4: 05 - 5: 28.
Momentum Usage: Excessive use of momentumsuch as bouncing a bench press or squatplaces stress on connective tissues that they may not be prepared for, leading to damage (5: 29 - 6: 17.
Recovery Steps and Protocols:
Isometric Exercises: These exercises involve contracting a muscle without moving the joint. During a 30-second hold, the load is distributed from the strongest parts of the tendon to the weakest, signaling the tissue to synthesize collagen and gain strength (6: 18 - 7: 20.
Implementation: Choose an exercise that mimics the movement causing you pain (e. g, a static bench press hold for shoulder pain or a wall-based knee extension for knee pain. Perform 3 sets, holding for at least 30 seconds (7: 21 - 8: 30, 9: 09 - 9: 30.
Routine and Progression: For the full rehab plan, perform 3 sets twice a day (morning and evening. To fix the issue permanently, continue this 34 times per week for 48 weeks. Some discomfort (3-4/10 pain) is acceptable, but ensure it does not worsen the following day (8: 31 - 8: 51, 9: 30 - 10: 05.

Man, this is really important stuff. I knew about isometrics, but I didn't understand the impact they could have on tendon strength/health. I've had supraspinatus problems since high school, with recurring tendonitis and partial tears that would fade over time. This video reinforces that I never really did anything to get at the underlying problem, so last year when decided it would be a brilliant time to try dumbbell flies, I suffered a full thickness tear that will NOT heal with time or exercise. Now I'm stuck with surgical repair (and a 1-year rehab) or just learning to live with a bad shoulder for the rest of my days. If adding a little bit of this to your routines can help prevent that, DO IT!

Never been on juice, I worked out natty for over a decade, 15 to 30 years old. I ended up snapping the tendon in my right arm that connects the bicep to the forearm, so painful and a horrible recovery, I am 39 now and still have not recovered properly after surgery to reconnect it. What they are saying happened to me, my muscles got stronger than my tendons, I had warning signs, I got tendonitis 3-4 times before it snapped. I can't emphasize the importance of strengthening tendons as well as muscles, don't be me.

Great overall video.
7: 56 I'd like to clarify that when you are doing static exercises to reintroduce force to tendons, DO NOT DO MAXIMUM EFFORT as that is what likely irritated the tendon in the first place. The clip shown here shows Jeremy doing what looks like maximum effort on the machine press, which can make someone think they have to do maximum effort to heal the tendon. It should just be enough force (pain free) to give the tendon a bit of a challenge. Maybe 3 to 5 / 10 of maximum effort.

Jeremy, I honestly love you for this. I have been feeling quite broken after dealing with a long-term injury, then another issue on top of it, and it has really started getting into my head. I was beginning to wonder whether I was getting too old to keep doing the activities I love competition ballroom dancing, weight training and Krav Maga. Your videos have given me hope that I can keep going, rebuild properly and continue doing the things that make me feel alive. Thank you, thank you, thank you.

In other news: most of the tendon issues I’ve ever seen are because people are literally loading their tendons. If you get painful knees from a hack squat, yes you can strengthen your tendons, but you also don’t stand a chance if your body position is causing several hundred pounds of load through your tendons. Strengthening them important but also just pissing on a bonfire if you’re lifting like an idiot

I did the biceps isometric hold, 90 degree angle, but that only triggered the unlnar nerve. Tingling in pinky and ring fingers next morning.
So no biceps holds for me. Same reason I don't do planks anymore, and for a long time already, the ulnar nerve playing up, tingling fingers. Never expected that these 90 degree holds would trigger the nerve just as well. Isotonic biceps curls never gave me this issue.

Really good video! Any time I've had a tendon injury the only thing that has helped it at all was really slow resistance training, similar to what you're talking about, but using flex bars or resistance bands. And the improvement was dramatic and quick which was quite the contrast after months of trying to figure out how to fix it with little or no improvement.

gym community is so lucky to have jeremy. Isometrics have been used in the athletics world in the context of tendon and joint health. I myself have to jump from gym communities to sports communities just to find out about the isometrics. I wouldnt have known isometrics if i didnt start doing sports. Jeremy is doing wonders for gym community right now

Amazing video and explanation. Im really excited to do these exercises and i hope ill feel better from it. I haven't worked out that much in life. I just started 3 years ago but there are still so many areas that i haven't been able to progress at all because the pain doesnt go away with regular muscle training.

This works for my body. Everyone is different, but I work out 4 days in a row (Sun-Wed) then 3 days off in a row (Thurs-Sat. Plenty of time for my body to recover, no fog or mental fatigue, lots of energy on Sunday. That is my sweet spot, great results but again everyone body responds differently.

pushups hurt my right shoulder, so do holds. Curls hurt my right biceps tendon and shoulder, even light weight. Not sure how to get started doing these when pretty much everything hurts my tendons. After 35, my elbows and shoulders just get injured all the time. And they don't heal.

I was excited to check out the app, went on the website and couldn't get any actual information without answering a ton of questions that we all know all lead to the exact same place. Even then, played the game, gave all the info, and now I still have no information but a ton of spam.

I just wanted to say that by watching your videos, I managed to go from 245 lbs to 173 lbs in four monthsgaining muscle mass while losing fat. Thank you so much for all the information; I always recommend your videos to anyone who asks how I achieved that physical transformation.

The timing on this video is perfect, dad here who finally got back into lifting. Had great strength progress but my shoulders are really acting up up last 5 days, this video was spot on. Gonna lessen the weight and have more reps and at the same time do these tendon exercises.

I have had several tendon injuries from 38 years of construction.
They never really heal, because they get very low blood flow, and tendon injuries are quite painful.
I tore the tendon in my right arm right at the elbow in 2012, its still hurts me to this day.

JeremyEthier, say you have tendinitis that flared up again. Should I stop the gym and focus on isometrics Or keep going to the gym and work through the pain while doing isometrics I have bicep tendonitis that I feel in the front shoulder, diagnosed by a doctor.

I had gone thru several Physical Therapists for shoulder tendentious with no luck. I finally went to a guy that basically gave me these types of iso exercises and it is finally better. Whenever I have some pain, I do these again and it gets better.
