The Kynett Gyro Ball Autostart Pro is the premium trainer for hands, wrists, and forearms!

Thanks to the Autostart system, you no longer need a cord to activate the ball. Simply twist, release, and start training instantly. This compact training tool uses kinetic energy: the faster you move, the more resistance you generate. No weights, no batteries! Just pure, self-powered training that adapts to your speed and effort.

The built-in LCD monitoring system makes every workout measurable and motivating. The display tracks your speed, time, revolutions, peak performance, and strength index, turning training into a fun and competitive challenge. 

Whether you’re looking to prevent injuries, recover from wrist or elbow issues, or simply add extra strength to your grip, the Kynett Gyro Ball is the perfect solution. 

Rehabilitation & Injury Prevention

The Kynett Gyro Ball is widely used in physiotherapy and sports medicine for both prevention and recovery:

• Tennis elbow  – controlled, pain-free strengthening of forearm extensors.
• Golfer’s elbow – gradual strengthening of flexors and grip muscles.
• Wrist injuries & instability – safe resistance to restore strength after sprains or overuse.
• Carpal tunnel syndrome – promotes blood flow and endurance of hand/wrist muscles.
• Shoulder & elbow rehab – supports kinetic chain training for rotator cuff stability.
• Climbers, racket sports, cyclists – ideal for sports requiring high grip strength and endurance.

Small but powerful: the Kynett Gyro Ball helps you recover, prevent injuries, and build lasting strength.
