Gym Fitness Hand Gripper Trainer 5-60Kg
Gripper, sometimes called Gym fitness hand gripper, they are primarily used for testing and increasing the strength of the hands; this specific form of grip strength has been called crushing grip, which has been defined as meaning the prime movers are the four fingers, rather than the thumb.
There are differences from brand to brand, but the common features of standard grippers are that they use a torsion spring fitted with two handles. The exact dimensions of these elements vary, as well as the materials used to make them; the springs are made from various types of steel, and the handles are generally made from wood, plastic, steel or aluminum.
How to use gym fitness hand gripper:
The user holds the gripper in one hand and squeezes the two handles together until they touch. Once touched, the handles are released and the movement is repeated. Variations of this basic movement include negatives [see below], and a variety of partial movements. For example, if the strength of the gripper is beyond that of the user, the user might apply maximum force, moving the handles as far as possible, even if the handles cannot be made to touch. Another partial movement involves using two hands to squeeze the handles within approximately 19 mm (3/4 inch) of each other, releasing one hand and then using the other hand to make the handles of the gripper touch each other. Negatives involve starting the gripper handles touching and then resisting as the gripper opens up, in an eccentric contraction.
