So, I've been shadow boxing a lot the last few weeks, trying to get my form back in gear, and I've noticed that my right shoulder tends to hurt a little afterwords. Not intensely, mind you, but enough to make me think that something's not as strong as it should be or isn't stretched properly. I've done the shoulder stretches and rotator cuff stretches that I was taught in middle school gym class (which always seemed to be fine enough), but maybe I'm missing something? Or could it be a problem with my shoulders not being as strong as they were when I started boxing?
So, this brings me to my question: does anyone have any advice on how to strengthen your shoulders and rotator cuffs? Also, advice on how to stretch these areas properly would be greatly appreciated.
