Abstract: Exercising the wrist and hand of an individual is achieved solely by the individual by anchoring the hand to a fixed support with the palm facing upward and the thumb and fingers free to move. The individual then grasps the thumb of the secured hand by the other hand and pushes the thumb laterally outward and toward the fixed support, thereby stretching the muscles, tendons and ligaments of the hand. Anchoring the hand to a fixed support is achieved by use of a C-shaped clamp, with one open end engaging the underside of the fixed support and the other open end engaging the palm side of the hand in the area between the carpal wrist bones.
