PST HMS slam ball. Designed for intensive exercises that involve dynamic slams to the ground. The appropriately selected external synthetic material and the sand contained inside ensure that the ball does not bounce. Slam-type training fully activates the kinetic chain, develops capability, endurance, and significantly shapes explosive power. This category of training suits any athletic activity that requires speed and high muscle strength, and is ideal for martial arts athletes. The ball is very durable and waterproof, allowing for outdoor training, while the special protrusions across its surface prevent slipping from the hands. This ensures a high level of comfort during exercise and increases movement accuracy. In addition to slam training, the balls are excellent for warm-up exercises, as well as those that strengthen our core. PST HMS balls are available in weights from 2 to 30 kg.
