Hi, my name is Coach Skip and I teach lower body engagement.
The larger the distance between your knees the more command you have.
Therefore, a balanced front leg lift keeps your front knee in front of your front hip.
Your lower body engagement occurs when you produce a balanced front leg lift, your shoulders open, and you stride.
Your stride prompts your lower body sends the ball into your target.
Concentrate on a balanced front leg lift, and the hitter needs to read location, ball speed, and movement.
