I don’t disagree with the volume statement. Front deltoids get trained in almost every pressing pattern regardless of angle. I’m a strength and conditioning coach, and from my experience, yes a good portion of the population has some sort of rotator cuff dysfunction, whether it be symptomatic or asymptomatic.
What I don’t agree with is the statement that shoulder work in the form of overhead pressing is the mechanism that leads to those injuries. From almost every case I’ve dealt with, it’s been horizontal pressing variations (bench press etc.) that leads to the most cases of impingement syndrome that I’ve dealt with.
In my opinion there’s too much emphasis placed on total pressing volume in general. Active release and PT on tight pecs, especially the pec minor, and like magic, the shoulder pain goes away. Not every case, but 95% of them I’ve encountered working with athletes of all types. Just some good for thought, and I love this type of dialogue. I’m an exercise physiology major and I love discussing this shit
