About two and a half years ago I seperated my acromioclavicular(AC) joint playing rubgy. I gave it ample time to heal before returning to lifting, and have had no problems. Recently (within the past month or so) my bench press has gone up and I’m at 285, which is the highest it has ever been.
I maxed out three weeks ago and have continued training since that time, but every time that I do regular grip bench press or dumbbell flyes there is a shooting pain in my same shoulder that I seperated. This only occurs on those two lifts and I never feel the pain otherwise, although my shoulder sometimes pops when I’m warming up/stretching.
Is it possible that I aggravated this old injury? Should I focus on some shoulder work to help strengthen my shoulders? Any help would be great
