It’s easy to build hand strength with this economical hand exerciser.

• For light resistance, loop a single 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, try 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.

Note: The wider the hand, the greater the resistance
