Head movement is the subject of this Skill Pathway. Your head doesn't remain still, so how and why does it move, and what keeps it still?
One of the biggest problems for players, especially amateurs, is how their heads move. The movement happens because they are trying to shift their weight.
Forces, not weight shift, are what causes your head to move. When you swing into your right heel, then into your left heel, and your left leg pushes back, your head moves as your body tilts. It is not because you are just moving it back and forth.
Mike stands on one foot and swings to demonstrate how his head doesn't move much as he pivots on one hip. He doesn't push off on his right foot when he changes direction and starts down.
It is vital to understand that you are not trying to shift your weight; you are trying to move force. Practice hitting on one foot to experience what it feels like to hit down into the ground instead of off the ground.
Correctly moving your body will make your head more stationary and not move around as much.
