This is the only forearm strength trainer we've found that exercises the muscles and tendons used in opening the hand. So if you play golf or tennis, play piano or guitar, spend much time on your PC – or use your hands in your work, you'll benefit from strengthening the hands.
And if you suffer from carpal tunnel, tennis elbow, or arthritis in your hands and fingers, Firm Grip can provide real relief from persistent pain. Slips on like a glove, can be used on either hand (notice there are two thumb loops!), and conditions the extensor muscles of the hands, wrists, and elbows.
Five bands may be adjusted through three degrees of resistance, individually for each finger. Just a few brief minutes a week of training helps hands feel, and perform better. Item #WS139.
