Hand grips are shaped like a "V" approximately three to five inches long with two metal "arms" connected by a central torsion spring. You grip both arms in one palm and squeeze your hand tight to compress the arms against one another, fighting the resistance of the central torsion spring. It helps in increasing finger, hand, and forearm strength. Ideal for sports that involve lots of wrist motions, these hand squeezers help you build stable and fingers and wrists. The foam-covered handles of these hand squeezers provide a comfortable grip and are hence very easy to hold and use. Apart from being a strengthening tool, these foam resistance hand grips are also excellent devices that can be used for stress management.
