Hey guys. Two years ago I had a bad motocross crash and separated my AC joint in my shoulder. I had an MRI done and it was stretched but not to the point it need surgery. I did physical for about 2 or 3 months and it did get better. After PT I wouldnt go more than half way down when I benched. Last winter I started to bench normally and was stronger than ever and my shoulder was fine. Well two weeks ago I was benching and it started hurting and hasnt stopped since. I cant lift and cant do much of anything with it. So what are some excercises I can do to strengthen my shoulder that wont hurt it? I have free weights and a weight stack with high and low pullys.
