I am at a loss for weight transfer stuff. My DD eliminated her stride to eliminate alot of 'noise', and it seemed to help. Not condoning it, she just has no clue on balance. Her body doesn't work that way, and she complains about not having any balance all the time. So i tried to eliminate the argument.
in any case, what it allowed her to do was focus on the pressure she was putting into her back foot. I am not sure if we have it correct, but I had followed Eric_F and his DD Maddie and her journey, and one thing he told me was the clockwise rotation of the back foot putting external rotation pressure on the rear leg. It helps the hips 'slide' over as the core torques the torso.
There is a golf video that i think Boardmember posted a long time back about 'the move' and it was on a sevam1 youtube channel (i have attached). I really think this can be used with both stride and no stride, but has helped my DD quite a bit. Gonna use it in my golf game too.
With any significant move backwards towards the catcher, my DD got all out of sorts. I wanted to at least focus on getting alot of the 'swing' part fixed, and then the pre and post stuff can come later.
still not sure if it is working or will help. HS ball just started this weekend, so we shall see.
If you get into the back heel, the move is an automatic. Or at least the reasoning of why to do it.
