Pro tip, don't listen to this guy. He is trying to sell you something, and that something is not optimal for anything that has to do with exercise. Only if you are part of the select few that have serious knee complications should you imbibe Dr. Seedman's advice. If a muscle isn't lengthening or stretching and is under load like in the squat here, it is performing an isometric action. If a muscle is lengthening under load like in the squat here, it is performing an eccentric action. Dr. Seedman knows this, he is not an ignoramus. He presumably thinks that co-contractions changes the definition of eccentrics or isometrics. It does not change those definitions. If you are co-contracting the hamstrings and quads in the squat, for example, if your muscles aren't changing lengths you're still performing an isometric action. He is trying to sell you a fake cure and wrapping it in jargon. Do not blindly accept what he has to say. The myopic focus on this exact method of squatting is suspicious because the 'best' method of squatting will necessarily include depth below 90* joint angles. Unfortunately for Dr. Joel Seedman, the past few years of research have blown up his pseudo-scientific justifications for ego squatting. He has the gall to say that with 90* joint angles we can overload our muscles in the most biomechanically advantageous position without any reference to the clear evidence that hypertrophy is directly mediated by tension and muscle length. Muscles taken through their full range of motion, especially their lengthened position, achieve higher tension and thus higher muscle growth and require less load to do so, reducing injury risk. Dr. Seedman likes to talk about biomechanics, but curiously leaves out the fact that, biomechanically, stopping at 90* joint angles in the squat necessitates the use of heavier loads in order to achieve the same tension to the muscle. Using lighter loads through a full range of motion is more challenging than using heavier loads in an ego-squat. Only difference is that your back will hurt more after ego squatting, rather than the musculature of the back, for example. You can try it for yourself: squat with 135lbs or 225lbs or whatever weight you might use, and take it to 90* joint angles. Then, do a few reps to the depth that your hamstrings and calves nearly touch. The difference is obvious. Dr. Seedman expects you to be uncritical about his claims because he talks in scientific terms. Do not believe him, he is trying to sell you something. Research range of motion and his other silly claims for yourself.
Where did you see that on isratel or telander? Have a brain for yourself, or try it out for 30 days and then make a conclusion. Stop being a brain dead person and repeating stuff you’ve heard
Very cool to hear the concept of agonist and antagonist coactivation explained through a weight lifting lens! In Yoga Asana this concept is called Bandha, with the word being related to “brace or bandage.”Many yoga asanas if performed properly naturally elicit coactivation of agonist/antagonist muscles forcing them to become synergists, creating “yoga” literally “to yoke” so they become greater than the sum of their parts. Two coativations I love that you might find interesting: hip flexion + hip lateral rotation (flexors and glute max). And another: axial rotation + diaphragmatic inhalation (obliques are the muscles of forced exhalation and/or axial rotation, diaphragm is main muscle of inhalation… coactivation of opposing respiratory muscles.
Mr. Seedman has been filling me with knowledge, his seed, if you will. My quarter squats have never looked so crisp, my eccentric concentric decline bodyweight sideloaded squats with chains on a balance ball has gone up 5 kilos, can't wait to see this movement replace weightlifting at the olympics. When women see me at the gym preforming a one legged reverse grip bamboo balance bar bench press, they react in what I can only describe as pure sexual lust, usually manifested in them immediately averting their eyes from me and walking away to do some eccentrically loaded cable rdls guided by the doctor himself. Doctor Joel Seedman has changed my life, I have a full head of hair again and my confidence in preforming a balance ball squat with chains and bands clearly shows how this alpha dominates the movement laboratory. God Bless
I only do landmine squats now because they dont f@#k my back. Just realised its a 90 degree squat where you start on an angle (so it looks more parallel). It's a shame such good advice could draw so much hate from those who are set in their ways.
He’s actually right especially for athletes with long arms all these full range of morph motion kings have short ass arms and they’re basically doing 90° anyway just look at a video of a benchpress with short arms and a barrel torso. They’re basically doing a 90° press.
No. I'm quite tall and also have a slightly large arm span than my height. 90 degrees does absolutely jack for my hypertrophic response. I switched over to deep range training - had to scale back the amount of weight I was using - and also included long/deep range partials training and I have noticed significant growth differences in a 8-week period. Also, this idea that you lose recruitment in your back muscles/lats when you you deeper in just untrue. It takes time to develop the extra range of motion under load, I mean, a lot of people don't even have this deep ROM passively. It is an approach that takes time to learn, and from a proprioceptor perspective, these takes time to adjust and adapt to deep range training to be able to provide feedback. You don't just switch over and it happens... it is a commitment to an outcome. You have to relearn the movement.
This sounds a lot like Jay Schroeder! What is "distinct" between you and his "methodology"? What do you think of the "extreme iso's"? And as far as "90 degrees" goes what about using this training for Olympic lifters?
big fan of what he did but some of the end range positions I was not a fan of. But in theory many of the principles were similar for sure. He paved the way for many coaches. Yes love 90 deg EI for hang version of olympic lifts. Great questions.
If you were trying to peak for vertical jump/sprint training would you transition from eccentric isometric training to more concentric style training to peak or keep them in the routine? Thanks
Depends on goal and context. But essentially cocontraction is bad for speed, should be minimized on the movements you do in your skillwork. Doesn't mean it should be avoided at all cost on all movement. You can work on balance and strength, and for that you do need as much muscle as possible to help, but when you introduce the velocity factor, you need to reduce it. If you wanted to simplify it and your goals were speed and power and power-endurance, i would train the antagonist separatedly and work to reduce your cocontraction to the smallest amount possible. If your goal was strict strength, then go all in on cocontraction.
To ego-lift obviously. This guy knows what he's doing. He's gotta make a living and he's not as knowledgeable or muscular as other science-based fitness influencers so he just makes it up and uses the most scanty and counter-intuitive paper tiger reasoning that falls apart with the slightest critical inspection. Embarrassing. You telling other people to get a job is ironic, Dr. Seedman. I say you should get a real job. Get real.
He either sucks at his job or loves to lie. He doesn't apply any context to purpose... The goal will determine the style of training and the types of exercises. 90's is only important for athletes who need to sprint and jump high. There is many other styles of training and MOVEMENTS that involve going past 90's. Saying "90 degree eccentric is the best way to lift" is not accurate because that statement has NO CONTEXT. It all depends on goals and purpose and Seedmans claim "this is the BEST way" is just plain stupid because what is "best" will depend on a variety of factors. Seedman just proves that not all ppl with degrees are going to be honest, sincere, and try to provide well rounded information.@@camdendavis284

It works. I have been to using the technique and there is no pain at all. And all the while I am building muscle.
that's so awesome, so glad to hear that thank you!!!

I'd do both actually
Had to see this again. Here's a question if you will- Why was Verkhoshansky so against isometrics by stating that "co-contraction" was a BAD thing?
Why not combine isometrics with plyos?
Depends on goal and context. But essentially cocontraction is bad for speed, should be minimized on the movements you do in your skillwork. Doesn't mean it should be avoided at all cost on all movement. You can work on balance and strength, and for that you do need as much muscle as possible to help, but when you introduce the velocity factor, you need to reduce it.

So on short… flex while i lift weights?
That bit about self correcting while under load 🤯 going to start using this👊👊
