After reading this, I decided that I should probably start out slowly, given that I’m not quite as strong as Magnus Samuelsson, and get the trainer model first, with 100 lbs of resistance. IronMind publishes books and online articles on the subject of grip training, including the well-known book, The Mastery of Hand Strength by John Brookfield.

Known around the world as 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. This is a great product for people just starting out and then great as a warm up tool when you graduate to the higher level grippers.In subsequent models, IronMind continued improving the accuracy, durability and appearance of the grippers.

In 2008 IronMind was criticized for changing the rules on how it certifies people who have closed its Captains of Crush No.

When I first started out, as I mentioned before, I was only able to close the trainer model (100 lbs of resistance) for 10 reps with my right hand and 6 with my left hand. We love using these grippers, they have very sharp knurling, some people find it a little rough, but it's great for stopping any slippage in your hands, especially when paired with a little chalk. Captains of Crush Grippers - What They Are and How to Close Them: guidebook by IronMind’s Randall J. Captains of Crush Grippers (commonly nicknamed " CoC") is a brand of torsion-spring grippers (a torsion spring fitted with two handles) designed, manufactured and sold by IronMind Enterprises, Inc.I used to think that it was all about reducing the range of motion so you could pretend that you could close the gripper. This is a set but it would be considered a no set on any other gripper because my hands are very large and very wide. 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.

This summer while I was training with a 24 kg (53 pound) kettlebell, I could barely do 10 single-arm snatches in a row. The descriptions of the grippers turned out to be very helpful in choosing the right model for my current strength level. A year or so later I have closed RGC 165, and recently also certed the IM 3, which of course is with a credit card set, which I also could not do back when I resisted learning how to set for MMS.We decided to give 4/5 stars on feel as they do feel superb but can be a little slippery without chalk.

After many months we finally finished the design and specifications and came through with our current line. IronMind has been involved in manufacturing springs for our hand grippers for over 15 years, and because we’ve been diligent in our pursuit of perfection and had plenty of good fortune along the way, our latest springs, introduced in 2005, once again raised the bar in terms of precision, durability, and appearance. Keep in mind these grippers are tough on your hands so if you have soft hands and want to keep them that way, these are definitely not for you. I was already pretty familiar with hand grippers, but was never terribly impressed when I used them.The goal of grip training is to train your neuromuscular system and not fatigue your muscles too much. Strossen wrote a book in 2003, Captains of Crush Grippers: What They Are and How to Close Them, to address some of the myths and questions surrounding CoC Grippers. The black rust proof coating on the springs not only adds to the performance and longevity of the grippers but also makes them look great! IronMind are a USA based company who produce some great grip training equipment, including the CoC Grippers.
