You throw them down...you pick 'em up again. You throw them down...you pick 'em up again! Yep...its that easy. Slam Balls (sometimes called Dead Balls) don't bounce. And thats the point! The typical use for a slam ball is to perform a squat to pick it up, engage the core as you lift the slam ball over your head as if you are doing a shoulder press. Then in an explosive action, you throw the slam ball back down to the ground.
