Hello, I am trying to maximize my weight in squatting, so low bar squatting is apart of my routine.  When I attempt to squat like this though, I have pain in my left shoulder. Even, when I use a light stick to practice form, I still seem to have ever-so-faint pain in my shoulder. I do not believe it is impingement, because I can lift my shoulder vertically without pain (most often). Also, when I Bench Press, I do not feel pain wither….very strange Now, I am doing shoulders dislocations now, so I have to see if the pain resides during the actaul squat. Any help is appreciated.
