Couple of questions:
1. When performing dips should my shoulders be as externally rotated as possible? I can perform the this way on the p bars but not on the rings, where I can definitely feel my chest being used more. Should I take a step backwards to gain the strength for the ring or is this nothing to worry about?
2. My right arm is noticeably larger and stronger than my left, and it has not been a problem yet but I would like to keep it that way. Any tips on balancing things out?
