Do you have an aching pain deep in your shoulder that bothers you when you're doing exercises in the gym - especially back exercises like lat pulldowns and rows? If you feel the pain in the back of your shoulder but have a hard time pin-pointing it then it's possible that it might be your subscapularis muscle - one of the 4 rotator cuff muscles of the shoulder. In this video my good friend and Sports Physician Dr. Baron shows us some tests that we can do on our own to figure out what's causing that shoulder pain when working out. We then discuss some common causes of subscap injuries, both in the gym and outside. Most commonly these injuries are associated with sports that have overhead throwing-like movements, including football, baseball, tennis or even javelin. After covering some of the common causes of this nagging shoulder pain, we'll then cover some things you can do to correct it. Welcome to Gym Pain, Problem, Solution.
