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.

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.

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.

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.

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!

They are a very solid build, good knurling and feel great to crush! Only getting CoC grippers now

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.

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.

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

As expected. 5/5

Son originales sin duda, el material de primera calidad, resistente, el agarre muy bien con el moleteado no se te resbala, bastante dificil de cerrar, pero vale la pena el intento, sin duda aumentará tu fuerza en el brazo.

Ottimo prodotto! Un piccolo appunto: l'impugnatura è in metallo zigrinato. Tenetelo presente, perché per poterle utilizzare ho dovuto mettere delle impugnature cave in gommapiuma sopra il metallo, perché quando si stringe forte la zigrinatura può far male alle dita, rendendo quindi difficile l'esercizio! Applicata la gommapiuma, nessun problema.
