It's easy to build hand strength with the economical Hand Exerciser. For light resistance, loop a rubber band around the top bar of the sliding finger grip. Attach additional rubber bands to increase resistance. Five rubber bands are included, each providing approximately 4 lbs. (1.8kg) of force. For even greater adjustability, choose the Deluxe Hand Exerciser. Two metal thumb screws may be adjusted to change the length of pull to best fit hand size or desired range of motion. The foam hand grip offers increased comfort on the palmar surface.
Optional, Color Latex-free Rubber Bands are sold separately. The wider the hand, the greater the resistance.
