The GRIPMASTER is our signature model. It's ideal for any athlete wanting to develop hand strength. Available in four different color-coded models of graduated resistance, GRIPMASTER offers both men and women an opportunity to dramatically increase hand, wrist, and forearm strength.
Light: Recommended for the average woman's hand and men preferring more repetitions at lesser resistance.
Medium: Recommended for the average mans hand.
Heavy: Recommended only to those requiring exceptional grasping power for martial arts, climbing or weapon retention.
