I’m saying hips move first. When instructing I tell the player the hips move first but would be almost undetectable without video. As in the above video I also tell them the hands are trying to move faster to catch up to the hips. Of course that’s not a conscious thought when hitting. Hands moving first is a flaw. Hands and hips at the same time is a gate swing. I try to use Miguel Cabrera mostly as the model.
Wait I thought the hands were the last to move? Your reasoning for lag? How would they ever catch up?
Do they really move last? See how the torso goes after the hands?
