My shoulder workout consists of military press, side lateral raises, and rear raises. The problem is that I feel like something is rubbing together or there is a popping sound in my shoulder joints. Ive tried it w/o weight on my adjustables dummbells just to try to figure out what the problem is and still feel a pretty bad discomfort. So Im thinking of just replaceing side raises, but haven't been able to find another exercise just as good for the side delt. I was hopeing u guys could help me out.
