Our SECRET WEAPON GRIP MACHINE is an exact replica of Joe Kinneys Secret Weapon Grip Machine.
Joe Kinney was the first person in the world to close the infamous Iron Mind No. 4 Gripper. (video?)
With this training device you can reach extraordinary results. The grips can be squeezed tighter than it is possible with common hand grippers. Additionally the negative-training can be arranged more intense.
Be warned: Most people give up the training with this device very fast. Are you one of them?
