The ISO Donut is designed to offer a way to further improve your grip strength. You squeeze the Donut as a fidget-widget or stress reliever. Option: With a small purchase of a 2nd Iso-Donut, the 2 Donuts can be used to help your punching skills. This added element provides a secondary isometric strengthening technique and helps to create the correct biomechanical positioning of the hand, wrist, and forearm.
