Hand strengtheners are used by people looking to improve their grip strength. These are most often used by people with active lifestyles such as rock climbers hikers, bodybuilders, tennis players, and other athletes, as well as musicians. But folks who are aging and have muscle decline or people dealing with repetitive stress injuries like carpal tunnel syndrome also find these to be very useful for physical therapy exercises, and they can even be used for arthritis or post-surgical rehabilitation. Stronger hand grip can help relieve tendonitis, joint pain, and other overuse injuries caused weak hand muscles.
