Start: Hold a ball against a wall at chest height, and aligned directly in front of the shoulder to be trained. Elbow slightly bent, body vertical with weight through centre of feet.
Movement: Press gently into the heel of your hand and bend your elbow, allowing your body to move towards the ball. Maintain a straight body line. Your shoulders and pelvis should remain parallel to the wall at all times.
Return: Press the ball away from you until your body is vertical once more.
