These hand grips were developed for athletes who want to take the training of their grip strength to the next level. These high quality all-metal hand grippers are made in 50 lbs. increments so that you can train your grip similar to training any other body part - by increasing resistance.

If you want to develop serious hand strength for a sport, or just want to impress your friends, then Bone Crusher hand grippers are the only choice for you! This is the perfect hand gripper for arm wrestlers, power lifters, strongmen, rock climbers, gymnasts and anyone else who wants to develop a strong crushing grip and massive wrists and forearms.

Bone Crushers are not affiliated with any other metal hand gripper on the market. There are other metal-handled hand grippers that may be of similar strengths and quality. But the differences is that we are one of the few to offer a lifetime warranty and a lower prices,

Although our hand gripper strengths are marketed in 50 lb. increments, these strengths are approximate. Our hand grippers are made with heavy-duty torsion springs. The actual strength of each hand gripper may vary as the "spring winding" effect increases the grip’s resistance slightly as the grip is closed. Great care is taken to ensure that each hand gripper spring is as uniform in strength as possible.

Bone Crushers are available in seven different resistances; 100, 150, 200, 250, 300, 400 and 500 lbs.
