Ball Slams Exercise
1. Begin in standing position with medicine ball overhead, back slightly extended and looking straight forward. Elevate your heels and stand on the balls of your feet.
2. Throw the ball down so it touches the floor about two feet in front of you, letting your heels touch the ground and knees slightly bend.
3. Let the ball bounce off the floor, catching it when it comes back up. Lift the ball back to starting position.
