Richman Trading Flex-O-Fist Hand and Grip Strengthener Exercise Rings

Simply squeeze the varying resistance silicone rings. There are three major training types: crushing, pinching and extension.  The extension exercise is simply an isometric pushing movement through the central hole of the ring; you cannot extend the ring at all. You can either gradually increase the resistance and difficulty of your training as your hand strength improves or alternate between the 3 rings in a single workout, giving you the benefit of interval training.
