We are proud to now offer the new GRIPMASTER PRO, a newly released upgraded line of Gripmaster, better than anything previously seen! It is slightly larger, more ergonomically constructed, and will better fit medium to large size hands.

BLACK PRO Heavy Tension larger hand gripper - 9 lbs / (8cm tall). per finger for Strong Hands. Recommended those requiring good grasping power for powerlifting, strongman, bodybuilding, rugby, climbing, or weapon retention. Bigger springs, thicker build and rubber tipped 'fingers'. Works great with a GREY or RED PRO for men with good sized hands.

Each finger of the hand is powered by a completely separate system of muscles and tendons located in the hand, wrist, and forearm. Most of the hand’s power is generated by larger muscles in the forearm while finer movements are controlled by smaller muscles in the hand itself.
Our wrist is the bridge which stabilizes the interaction of the hand & forearm. The GripmasterPro is basically a tool that exercises each finger individually. It strengthens fingers, hands, and even forearms. It's unique design allows you to isolate your digits and exercise each one on its own. Your hand is really five separate systems which work in seamless unity. The only way to develop superior strength, endurance, and coordination in your hands is to challenge and develop each finger individually.
Once you exercise with the new GripmasterPro you’ll notice an amazing difference almost immediately. The separate system which operates each finger will awaken and strengthen.
