Beyond the Range Training
-
Beyond the range training consists of working with a gripper that has a handle filed down to increase the distance the spring must be compressed to close the gripper by up to 1/4”. This serves to increase the resistance of the gripper at the close, as well allows for training closing the hand further than with a normal gripper. Often used when doing overcrushes or strap holds, this form of training is done to maximize strength at the gripper close.
Filing a gripper voids the warranty of all gripper manufacturers as it increases the possibility of the gripper spring breaking. Caution should be used when working beyond the range with filed grippers.
When filing a gripper, be sure to file down a single handle, removing a small bit of material at a time. Resistance will increase quickly. Filing both handles will result in the palm getting pinched between the handles during the close. An inexpensive solution for filing down a gripper handle is to use a bastard mill file, which can be acquired at a hardware store for a few dollars.
