I can see what I’m trying to express in just about every model you’ve shown; except golf.
My last thought on this is if the hands move first and they’re faster than the torso they will be impeded somewhat by the torso. At best they will move at the same time, a gate swing.
The thought may be hands first but the hands don’t move first.
Like I said kinematics are what you’re describing(motion). What I’m describing is how to apply(create force)to get what you see. As coaches we need to know how to create not describe the action. Right?
Don’t forget, force creates motion..
