The gold standard for building and testing hand strength.
Captains of Crush Grippers are the single most important grip strength tool you can choose for the fastest route to the strongest grip.
CoC No. 1: If you've already been working out with grippers, start here; most people who lift weights can't close it at first.
Please see our product pages as they are available in 11 different strengths, from 60lbs to 365lbs.
