I watched "Made in Germany" a dvd by Marcus Rhuel. In it he says he can't back squat anymore cause he is too big. He focuses more on front squat and leg press. I have heard this from other people, esp SHW powerlifters complaining about how much stress the back squat puts on the shoulder.
Just wanted some thoughts and experiences on this.
P.S. I have heard some guys get cambered squat bars to alleviate this problem.
