The gyro ball is a highly effective and modern fitness device designed to increase wrist, forearm, and finger strength. Its internal gyroscopic rotor generates power through rotation, helping to strengthen hand muscles completely naturally without any battery or charger.
Key Features:
Auto-Start Technology: No ropes or extra tools needed. Simply wind the rotor in the direction of the arrow and release to start.
Speed and Resistance Control: The faster you spin your hand, the higher the resistance and pressure generated from inside the ball (capable of creating up to approximately 15-18 kg of pressure).
Sturdy and Safe Design: Made with a premium quality zinc alloy rotor and a durable polycarbonate shell. Features non-slip silicone grip all around for a firm hold.
