PST HMS are slam balls designed for intense workouts that focus on dynamic striking against the ground. The carefully selected outer material and the sand inside ensure that the ball does not bounce. Slam training effectively activates the entire movement system and is beneficial for any sport that requires speed and high muscle strength, making them an ideal choice for martial artists.

The ball is very durable and waterproof, featuring special tabs distributed across the entire surface to prevent slipping from the hands. This design provides high comfort during training and enhances movement accuracy.

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