Roll shoulders — how it works

Each clip is one roll, the boxer facing the camera: from just before it starts until just after the boxer comes up, on a loop. Rate whether the shoulders rotate through the roll — turning with it and coming through — or stay square. The timeline shows the guard before the roll, the roll and its lowest point. Keep your scale the same throughout: Examples has one clip per rating.
