Captains of Crush Grippers
The Gold Standard for Building and Testing Grip Strength

For 30 years, IronMind’s Captains of Crush Grippers have been a staple of grip strength training, from the gyms of Strongmen, weightlifters, fighters, and football players to everyday athletes of all sizes and skill levels. Nearly every measure of performance is affected by your ability to lock on, hold on, and maintain your strength, and CoC’s offer a time efficient, customizable method for getting in the reps, seconds, kilos, and speed that translate into superior grip strength.

All Captains of Crush grip training tools are Made in the USA and feature knurled, aircraft-grade aluminum handles with IronMind’s exclusive, proprietary GR8 springs. These are not the old-school import grip tools that require endless repetitive reps while sitting in the office or watching TV—they are precision engineered to develop maximum grip strength in minimum time.

There are 10 different gripper strengths to choose from, ranging from the Captains of Crush Guide (60 LB of resistance for beginners, seniors, easy warm-ups, etc.) up to the expert-level Captains of Crush No. 4 (365 LB resistance). Rogue is also offering the CoC in four available package options:

  • Beginner Set: Guide (60LB), Sport (80LB) and Trainer (100LB)
  • Men’s Set: CoC 1 (140LB), CoC 1.5 (167.5 LB), and CoC 2 (195 LB)

Rated 5 out of 5 by from I got them all thru #3 and the verdict is... I thought I was strong. Boy was I wrong! Lifting 3 years, dl 340 weight 155lb 21 pull ups blah blah....couldn't close number 1 on day 1! No joke. 2 months later I'm closing #2 and 2.5 past parallel. So the verdict? The guide is my favorite! I use it the most to warm up and down. Since I have them all (almost) I do enjoy doing 10 reps then moving up to the next 10 reps etc until I get to the one I can't get 10 on and lastly try to close my challenge gripper. It's been an amazing 2 months. I closed the no 1 for 81 reps yesterday remember I couldn't close it at all a month ago. It's awesome quantifying progress!! Important not to overtrain. I'm doing 3 grip workouts a week with rest in between. I used acrylic paint markers to color the springs in order of my karate belts when I was younger. At a glance I know which is which and I'll use the guide sport and trainer the most. The others are for workout days only! Verdict: get grippers lower than you think you need. You'll have to close one in good form 15x before moving up to the next. Even after you're playing with 2.5 and up you'll still need warm up grippers and even the trainer is no easy close. Start low and earn that next gripper. Close a 3 in the official way and get your name on ironmind's site forever! Happy crushing!
