get your hands back, away from your body, behind your shoulder. Get your elbow relaxed, but ready to throw the bathead. get wide and on your backside. Seperate your hands from your stride- small stride, move hands back slightly. But definately do it definitively and aggresively and get good at it. As your hands move back, your back knee moves under. You shoulders stay locked in and your hands stay back as your knee moves under. Make sure your back knee is driving your front feel into footplant. Heel timing. Then swivel the elbows and let the bat go backwards.

Keep the bat in a deep grip in your hands.
