The inSPORTline 25821 hand strengthening ball uses a gyroscopic mechanism to train the palm, wrist and forearm. As it spins, the internal flywheel creates resistance, which increases the faster the ball spins.
The shaft is made of steel, while the outer casing is made of hardened plastic. It has a rubber anti-slip ring around its circumference and can be used in sports such as tennis, squash, golf and mountaineering.
