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

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.

Well worth paying the extra for a quality product. It is a lot harder than it looks as even my son struggles with them so more practice required before we move on to other versions but can't fault them. Like other reviewers said there is a bit of a squeak at times but nothing that WD40 doesn't fix. Don't waste your money on cheaper versions, would totally recommend these. Excellent service and delivery as well!

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.

C.O.C Sport Gripper (80lbs.)is a nice light gripper for re-hab or keeping arthritis pain at bay. High reps to force the blood into the hands, keeping them healthy, relieving pain ... and giving you big forearms to boot!

I rate this product very highly as i use it daily and i am noticing a significant difference in grip strength. However this level is not 'very' hard to close and therefore is good for high reps but i would recomend a slightly higher gripper, although i made the mistake of assuming that i could skip a few and my secound one was a 195lb gripper which is a number 2 C.O.C which is much more of a challenge and i am mm away from a proper close with my right.

It’s very well made. The sport model is easy to close and for me this is a warm up gripper before moving onto the harder models. The trainer which is the next one up is considerably tougher to close.

I bought this as I found the heavier ones were a bit difficult to close in higher rep ranges. I've found that using this gripper frequently has improved my grip and allowed me to move onto grippers with higher resistance.

ممتاز جدا وماركة عالمية وجودة عالية

J'ai bien reçu les grippers. Nickel, j'avais déjà des Trainers, mais j'ai pris des CoC Sport pour le warm up. Ils sont solides, confortables, bien en main et beaucoup plus qualitatif que les grippers de base.

Excellent grippers! Recommend

Nothing but the best it's the industry standard, extremely high quality. Great product!

My mate got these. He can do the all three although the last one is challenging for him so it is worth it for him as he got them to improve his grip strength. As for me, I can do the lightest one and so I too am working on my grip strength. These are made of metal and seem quite sturdy to me.
