Hand Grip

Step 1. A spring-loaded hand grip trainer for building grip strength and the forearm flexors.

Step 2. - Position: hold the hand grip firmly in one hand.

Step 3. - Squeeze: close it as hard as you can, trying to make the handles touch.

Step 4. - Release: hold the contraction for one or two seconds, then open your hand slowly and under control, resisting the spring.
