The new Gala Jump trainer is specially designed to improve the individual attack technique of volleyball players. By means of 2 elastic cords, the ball can be held in a fixed position. This position depends on the level/age/length of the player and has to be set by the player himself. Under always the same circumstances the player can train his launching and striking technique.
