The medicine ball perpendicular rotational throw is a great exercise for developing rotational power. The athlete should start 2 to 3 feet away from the wall with their shoulders perpendicular to the wall and the ball by their waist. They need to rotate their trunk away from the wall and initiate the throw by attacking their hips toward the wall. Cues I use here are back flat, chest up, and throw the ball with your back hip. I recommend 3 sets of 5 repetitions each side.
