The RENEW FORCE® Gyrrall gyroscopic ball with autostart and LED backlighting is a compact tool for strengthening the wrist, forearm, and grip. It uses the centrifugal force of the rotor and offers intensive resistance training up to 20 kg at speeds up to 21,000 rpm – ideal for sports, rehabilitation, and relief after long hours of computer work.
The gyroscopic ball works on the principle of inertia and the rotor’s centrifugal force – the faster you work your wrist, the greater the resistance the device creates. This makes it easy to adapt the training intensity to your current fitness level and goal, whether you want to improve grip strength, joint stabilization, or support recovery.
Who it is suitable for:
- Athletes – improving grip strength and joint stabilization
- Musicians – better precision and coordination of hand movements
- Computer work – reducing muscle tension in the hand and forearm
- Rehabilitation – supporting recovery of the wrist and forearm
LED backlighting visually responds to rotation speed – the higher the rpm, the more intense the light. Autostart lets you start without a cord: simply rotate the rotor a few times in the direction of the arrows, release it, and then smoothly increase the speed with circular wrist movements. Price is for 1 piece.
