Tonkey Original Heavyblock Pieces (weight from 1000 to 5000 g)

HeavyBlock variable-weight cubes are a valid and safer alternative to traditional rigid dumbbells: if the HeavyBlock were to hit a body part during exercise, there would be no significant physical consequences for the user. The weight can vary from 1 to 5 kg, depending on the amount of water or sand added.

Easily used with both hands and feet, they can be filled with water or sand to calibrate the weight according to your needs: from 1 kg to 5 kg. Their use is particularly suitable for programmed muscle training and harmonious body development.
