PST HMS are slam balls designed for intense exercises that involve dynamic hitting of the ground. The properly selected outer material and sand inside ensure that the ball does not bounce. Slam training effectively engages the entire movement apparatus. This type of training is beneficial in any sport requiring speed and high muscle power from the player, making it an ideal choice for combat sports athletes.

The ball is very durable and waterproof, with special tabs located around the entire surface to prevent slipping from your hands. This design ensures great comfort during exercise and increases the precision of movement.

In addition to slam training, the balls are also excellent for warm-up exercises and for strengthening the body. PST HMS balls are available in weights ranging from 2 to 30 kg.
