Roll legs — how it works

Each clip is one roll: from just before it starts until just after the boxer comes up, on a loop. Rate whether the legs take the body down (the knees bend) or the dip comes from bending over. 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.
