The gyro ball is an extremely effective and modern fitness device to increase wrist, forearm, and finger strength. The gyroscopic rotor inside generates power through rotation, which helps strengthen hand muscles completely naturally without any battery or charging.
Key Features:
Auto-Start Technology: No ropes or extra tools required. Just spin the arrow in the indicated direction, pull and release to start the rotor.
Speed and Resistance Control: The faster you move your hand, the higher the resistance and pressure generated from inside the ball (capable of generating up to about 15-18 kg of pressure).
Sturdy and Safe Design: Made with premium quality zinc alloy rotor and durable polycarbonate shell. Features non-slip silicone grip around for a firm hold.
