The Stramme Matz is an excellent fun and leisure game. The blue bags are pulled over the arms, stretched very tightly, and the game can begin. The play bag filled with plastic granules floats on the water. So you can also play on the beach and in the swimming pool. The Stramme Matz is a setback game without bulky clubs and fits in any jacket pocket. The game promotes eye-hand coordination and strength regulation. Depending on how tightly the Matz is stretched, the impact force can be varied. The sturdy matzo is also suitable as a handy and effective therapy material. Due to the constantly tensioned surface of the elastic fabric, seldom used muscle groups are targeted. Tensioning the cloth strengthens the muscles of the arms, upper trunk and upper back. In senior sports, the firm Matz is ideal for stool gymnastics. In addition, reaction, endurance and coordination are trained.
