Hello everyone! We all know that most power comes from upper arm rotation + forearm pronation in smashes and clears. But i was wondering how much upper arm rotation is actually needed? In many technique videos step by step instructions the elbow raises unnaturally high (or at least it feels that way for me). Someone who understands this could explain it to me In conclusion my questions are: 1. How much upper arm rotation is needed for smashes and clears? 2. How high should the elbow raise during the rotation?
