I watch all of his videos, they are really good. Great stuff when it comes to shoulders..
He's on target with a lot of this stuff. Some I disagree with.
If you want someone who really knows his stuff is this doctor of physical therapy who was the therapist for the Mets baseball team. You can catch his stuff on youtube on Athlean-X. I wish I had someone like him to give advice to me through the years regarding what exercises are bad for your body. Bodybuilders just keep doing stuff because of tradition and as a result it seems everyone eventually gets the same injuries like those to the shoulder that are accelerated through unhealthy movements. Zane, Draper, Arnold, Lou, Corney and a ton of others have shoulder operations. Did it need to happen? How many bad knees, backs, hips and elbows? You can lower the percentage of getting these injuries by putting the odds in your favor by not following the same old bodybuilding traditions like pouring the pitcher dumbbell delt laterals and chest dumbbell flies. So much more than the two mentioned. I have a partially torn rotator cuff in one shoulder and a torn labrum in both. As a result I gave up the barbell bench, barbell incline and dumbbell flies for the most part. I found declines hit my chest better without any shoulder strain.
