GRIPMASTER 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.

Prohands hand & finger exercisers are made to strict manufacturing standards using only the higest-quality components -- ABS plastic, Stainless Steel Springs, and FDA-approved Santoprene.

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.
