> > I would like to get your thoughts on a linear negative move. In looking at a number of the college softball players, their negative move is a weight-shift back towards the catcher and then the stride and then into rotation. I know in your videos you demonstrate a counter-rotation of about 30 degrees for the load (negative move). Just curious as to your thoughts on this more linear type of load?

I think you will find that most coaches that promotes “you must go back to go forward” or “walk away from the hands” have also bought into the “Crack of the Whip” theory for generating bat speed. This theory contends that the energy from a forward weight shift and straight extension of the hands causes the bat to snap around like the cracking a whip.

Therefore, all the linear cues based on the theory are misleading. This illustrates why I find most discussions on swing mechanics to be pointless unless both participants first agree on what forces are actually responsible for inducing bat speed. Once those forces are agreed upon, then a constructive discussion of the swing mechanics that most efficiently produces those forces can occur.

> I’m not sure I’m understanding your comments about the cues "you must go back to go forward" and "walk away from the hands". In my opinion having the hands move back towards the catcher during the forward stride has multiple benefits, one of which is obtaining early lead arm extension and the promotion of a semi-circular hand path.

>>>1 problem I have found with those cues especially on the internet is that you can do them just as they sound and be all wrong.You can take your hands back toward the catcher and doing the opposite of curling in ,the catcher is away from the body and back you load your hands more inline with the body and back than away from it.Depending what position the hands are in to begin with walking away from them may not give a proper load,again if you start with them away from body and back theen keep them there and stride ,you will lextend the lead arm bot not get the upperbody loaded.I like to think that we have to load the hips and the core this is what needs to feel coiled so it can uncoil,it has to stretch so it can fire or snap back.I like to try to get hitters to achieve a lead hip cock,show the rear pocket to the pitcher,this has different degrees for different hitters and never let eyesight by both eyes be compromised by your load or it is too much.Last a simple pull back by the elevated rear elbow back toward the dugout behind them will load the upper body and core,it properly allows you to walk away from the hands but they do not go back straight or toward the catcher
