The Multi Training Ball is a perfect tool to perform various exercises, in-group or individually. With 1 Kg weight, great bouncing capacity and a very good grip, this product will grant an ideal load for several sports activities, such as basketball and volleyball. It can be inflated to increase its bouncing or filled with water to increase its weight (up to 5 Kg), extending in this way the range of possible exercises. The water-filled ball has the same features as a medicine ball and it is suitable for a higher impact training.
