Designed for progressive overload, the CoC series offers 11 resistance levels (up to 365 lbs). The Sport model helps users build foundational grip strength before advancing to heavier grippers. The compact size fits in a gym bag, making it ideal for rock climbers, powerlifters, and martial artists who need crushing power.

The Captains of Crush (CoC) Gripper is the gold standard in grip training, trusted by elite athletes and strength coaches worldwide. The Sport model (100 lbs resistance) is perfect for beginners, featuring aircraft-grade aluminum handles with aggressive knurling for a secure grip. Unlike cheap plastic grippers, the hardened steel spring provides consistent resistance that won’t weaken over time.

IronMind backs this gripper with a lifetime warranty, a testament to its durability. Users report noticeable forearm and finger strength gains within weeks. While pricier than generic brands, the CoC’s precision engineering justifies the cost for serious trainers.
