PROHANDS Gripmaster

GRIPMASTER is our signature model. It is ideal for any athlete or musician wanting to develop hand strength, dexterity and endurance. GRIPMASTER isolates and strengthens each finger using spring-loaded finger piston technology. Quickly builds hand, wrist and forearm strength. We offer five color-coded models of graduated resistance.

Note: Hand specialists recommend lower resistance and more repetitions rather than higher resistance and fewer reps.

Important: always exercise slowly and cautiously. If you experience any pain, stop immediately and see your doctor. Excessive use may cause pain or injury.
