These are meant for one thing - slamming hard onto the floor or ground. The slam exercise works your back, legs, arms, shoulders, abs... And doing slams is a great way to release your frustrations and unload that excess energy.
Rage's Slam Balls were modeled after the popular Slammer balls for their toughness and good design. Don't use a regular medicine ball for slamming - you will destroy it!
The air valve allows you to adjust the rigidity with any bike pump to just the level of low/no bounce that you want, depending on your preference or the surface you're slamming onto.
