Captains of Crush Grippers are the gold standard for building and testing grip strength.
Very often grip strength is the limiting factor for performance, whether it is a 1 rep max deadlift, Fran, or rope climbs. The U.S.A. Made Captains of Crush Grippers are the best way to improve that grip strength and truly realize your potential.
There are 11 strengths so you can get on a linear progression like the rest of your strength training. Rather than banging out hundreds of repetitions and ending up with an overuse injury and no real improvement in grip strength, you can train in small doses with adequate rest, just like your powerlifting training, and get results.
