Stand in the power stance with the ball held at waist height.
Keep your core muscles tight throughout and maintain a slight flex through your knees.
Raise the ball up above your head and then drive it downwards into the floor using an overhead grip.
Maintain control of the ball on the return and guide it back up to the overhead position before driving it back down.
Ensure the downward drive is performed using good technique, not arching through your back.
Maintain control of the ball throughout all phases of the movement and keep your core muscles fully engaged.
