This exercise is designed to be used specifically with Slam Balls. Slam balls help you improve core strength, conditioning and explosiveness by maximizing your full body.
Start with feet shoulder-width apart and knees slightly bent, gripping the non-bounce slam ball with both hands in front of the chest.
Lift the ball overhead, fully extending the arms and keeping the back straight.
Reversing the motion, slam the ball down on the ground as hard as you can, making sure to bend the knees.
Drop down to push-up position, placing palms on the ball. Knees or toes should be on the ground behind the body. Complete the push-up and then explosively jump back up, reaching the hands overhead as you jump.
