IronMind Captains of Crush (COC) Hand Gripper - The Gold Standard of Grippers | The World's Leading Hand Strengthener

Warning. These grippers are extremely tough. In retrospect I should have started with the No. 1s. I bit off just slightly more than I could chew. I can curl over 30kg (single arm), and so I thought I'd be able to skip a step. Wrong! However after two weeks I am just about acheiving a close! The quality of the grippers is first rate. They are finely milled, knurled, and crafted from rugged materials. This is an excellent product and it is plain to see that once you are able to complete your sets with this you will have a powerful grip. Thoroughly recommended. See the ironmind website for training tips.

I’ve been using these for a few years now, and they’re as good as it gets. The quality is outstanding, and they’re well worth the price. I started with the Sport level and now have the No. 1 and No. 2 as well, and each one offers a strong, reliable challenge. They’ve helped me significantly improve my grip strength at the gym and have even alleviated my RSI. No other grippers I’ve tried compare in terms of quality and durability. Highly recommend.

They are an amazing grip strength tool, harder than you think if you have only been used your dad's grippers,! Many of my friends and family have been humbled by the captain's of crush #2 gripper, me included!! Just about close it after two months hard training. If you're serious about grip, invest in one, or a couple of these!

Good strong materials and build, should certainly last. Can feel uncomfortable due to the steel but that could be subjective. May be a bit overpriced but still useful for what they are.

Bought the CoC Sport hand gripper, as a high repetition / warm up tool. Excellent quality, with enough tension to challenge most people not used to grip / weight training. The great thing about the CoC range, is that you can progress quickly, once you have improved your grip strength on a particular gripper, there is always the next gripper in the range, should you wish to progress. Not cheap, but whether you just want to improve your hand grip strength a little, or you wish to build massive grip strength, for powerlifting or strongman, I highly recommend the Captain's of Crush hand gripper range.

There is not much to say about this product except that it is done right, machined and built very well and works like a charm. I will more than likely purchase a model with more resistance down the road, and it will surely be from the same company and from the same product line too, there really are no issues to improve upon in my opinion.

Ordered from Vallhalla fitness. Had some shipping issues which they worked very hard to fix. Great company and I would use them again. Fantastic grippers. Generally regarded as the gold standard until you get up to the level of the absolute freaks closing big mash monsters. Even people who train with other brands use CoC as a benchmark to gauge progress. I started being able to close the #1 and #1.5 with both hands. So I’m waiting on a 2 to arrive as a goal gripper. If you lift weight already I’d start with the 1 and skip the lower resistances. There are cheaper brands available and you should use them to “fill the gaps” between Captains of Crush. I’d recommend getting these first

These are great grippers. Better than any other brand. That said, my T (Trainer) set only lasted 11 months before breaking. I will buy the next level up, but it's a bit disappointing that they snapped.
