The IronMind Captains of Crush Trainer is the 100-pound hand gripper that everyone who takes grip seriously owns — the benchmark gripper against which all other grippers are compared. Knurled aluminum handles that don’t slip when sweaty, precisely calibrated spring tension, and a closing feel unlike the mushy, uneven pressure of commodity hardware-store grippers.
The Trainer (100 pounds) is the introduction to the Captains of Crush ladder — a closer-than-it-looks challenge for most adults and a necessary step before the harder levels in the line. Build up to closing it cleanly for reps, and genuine grip strength will follow as a byproduct. Strongman competitors, arm wrestlers, and climbers all train on the CoC scale.
IronMind has manufactured grip equipment in Nevada City, California since 1988. The company produces the official grippers used at World’s Strongest Man, has been the grip-training standard for decades, and still machines, springs, and assembles every gripper domestically.
