Slam Balls are perfect for developing core strength and explosive power, and can be used to develop virtually every muscle group in the body. They are versatile enough to be used for wall balls and other auxiliary medicine ball movements. Slam Balls are designed for slamming from above your head into the ground, therefore durability is required. The outer layer can withstand even the toughest of beatings with reinforced seams and seals to prevent any leakage or bursts. Each ball has a sweat-resistant textured surface to enhance your grip during a workout. It’s soft and absorbent, so won’t bounce back up.
