The gold standard for building and testing grip strength

If it ain't broke don't fix it. CoC's were used by the strength fiends and strongmen of old.  The difference between a weak and a strong grip is the difference in reps, seconds, kilos, and speed. Nearly every measure of performance is affected by your ability to lock on, hold on, and maintain your strength.

Captains of Crush Grippers: Maximum grip strength, minimum time.

Made in the USA.


Forget about the traditional approach to training with grippers - banging out endless reps while driving or watching TV - as it will do little to improve your grip strength but a lot to shorten the life of your gripper.
