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

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.

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.

Great Product - simply the best Grip Developer. Many of the grip developers on the market are low resistance and flimsy. If you are a hardcore lifter then this is the product for you.

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.

Great product well worth it

Great job

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.

they are just right for the person I got them for he will have them christmas

Wife has small hands and couldn't close the 100lb set . Got her the 60lb for Xmass she can just close em so it a good work out and confidence builder to get her to the 100lb set . Great quality and feel nice in the hand .

It's the big daddy of all iron grippers. Expensive, but this is what the champs use. If you can afford it, go for it.

ممتاز جدا وماركة عالمية وجودة عالية

Those grippers are well-built and high quality. The knurling is perfect, just add a bit of chalk in your hands and you're good to go! Oh, and add a bit of oil in the spring.

As expected. 5/5
