This is why it's a stupid idea to insist on an exercise blindly for everyone.
I have a torn right labrum. It would be a stupid idea to try this exercise for me. As of now, I'm almost ready to try a regular bar squat. For five months I've been restricted to safety bar squats.
Not all full body exercises are great for everyone. Some will benefit, some won't.
Currently I can squat over 500 lbs with the safety squat bar off a below parallel box. The weight necessary for me to make any kind of gains would tear the hell out of my shoulder.
