The Wrist Ball Powerball Classic 250Hz is a perfect accessory for strengthening hand muscles, especially the wrist and the forearm. This is a gyroscopic ball – when spinning, the flywheel inside the ball can generate up to 18kg of gyroscopic resistance. The more you spin the ball, the greater the resistance. At lower speeds, the wrist ball is suitable for beginners or those recovering from a hand injury. It also helps relieve tight muscles.
The Wrist Ball Powerball Classic 250Hz is suitable for everyone. Apart from strengthening hand muscles, it also helps relieve sore or tight muscles. It has become popular with manual as well as office workers (who suffer from wrist and forearm pain as a result of using a keyboard and mouse every day), musicians and professional drivers.
