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

Speedy delivery & packaged just fine - especially good that they can be posted through the letterbox. I’ve had all sorts of different grippers over the past couple of decades, almost all pretty cheap & very, very easy to close repeatedly. A couple of years ago I bought a ‘heavy grip’ that was a cheap imitation of the Captains of Crush. It was apparently rated at 200lbs, which I couldn’t quite close fully, so I was looking to find something to help build up to it. I must admit that I was drawn to the CoC grippers via some YouTube videos where they were testing folks grip strength (Jujimufu, Brian Shaw, Brian Alsruhe...) & decided to go for the CoC #1, since I figured I was already close to getting 200lbs, so 140lbs should be easy... Guess again. Well, I still loved the quality of this gripper, so almost immediately ordered the Trainer, to give me a lighter weight to warm up with. Pleased that I could then close that (100lbs), but decided to round things out by also ordering the Guide (60lbs), as my wife & kids were also now interested in getting their grip stronger, but they could hardly budge any of the heavier grippers. The lightest two were a bit squeaky, but that was soon remedied with some 3-in-1 oil application. We’ve also now got some really light squishers & finger bands for extensions too Overall, we’d definitely recommend the CoC family of grippers.

Expensive but excellent quality so worth it. It is the trainer model but don’t under estimate that, it’s still a tough model to master as you work on your grip strength. Highly recommended

I bought the trainer (beginner, 100lb) version of these. I'm no weight trainer and aged - just - in my fifties, but I could almost close these from the off. Almost. I would reckon these are a good starter for the majority of blokes. I was inspired to buy them after listening to a podcast of the Tim Ferris show featuring Pavel Tsatsouline who eloquently explained why having a strong grip leads to much greater overall body strength and fitness. They're expensive for what they are, but are real quality and feel pleasing to work with. I would agree with another reviewer who said the grip handles are quite abrasive, but maybe that will prevent overworking with them in the early days. All in all I'm very pleased with the purchase.

I placed an order for the Captains of Crush hand grippers because I had 40kg hand grippers that were too easy to train with and I wanted to take my grip strength to a higher level, I researched various brands and the Captains of Crush brand was the stand out option, when I placed the order with Valhalla fitness, (despite being a busy time of the year) the order arrived in double quick time and the product was in perfect condition, when I tried using the grippers it was apparent the excellent quality of the item and the required grip strength was up a step up, overall I consider the purchase great value for money and when I look to buy another hand gripper I would look to order again from Valhalla fitness

I'm no expert but it feels sturdy and robust and looks great. I haven't had it for long so can't comment on how robust it actually is, but I hope it's going to last much longer than that flimsy adjustable one I had which went up to 40kg. The grip's knurling can chafe and they squeak when used, but apart from that, there's not much I can say bad about them. I'll have to use them more to find out how good they actually are.

If you’re looking to train your forearms, then you really can’t go wrong with these grips. I’m certainly a beginner and currently not weight training. So, these are ideal for where I’m at currently with grip strength. They’re not easy by any means, but they’re not impossible either. I’m slightly stronger on right than on my left. At the start I could manage to maybe close them once on the right and not at all on my left side. Having used them on and off for roughly two months, 3-4 times per week. I worked my way up to closing the right side 5-6 times and the left 2-3. Unfortunately, I’ve not been using them regularly enough to see the full benefits of the training. But I’ll certainly be starting again on a training program with them. As some have mentioned they do start to squeak after a while. I haven’t applied anything yet to prevent this but will be using some of the oil tips in this review section to remedy this issue. It doesn’t diminish their quality in anyway in my eye’s either, so it isn’t a big deal. One thing to note – If you don’t have a manual job and sit at a desk typing for the most part of your job. Then you may find the grips a little uncomfortable or rough on your skin at first. It does become easier, and you won’t notice it after a while either, so isn’t too bad. But just bare this in mind, at the start it may be a little off putting for some. Highly recommended

Bought the trainer and quickly moved up to the 1. I still struggle to close the 1 so greatly improving grip strength is definitely going to be a long haul effort. These feel strong and durable and give a good high level of resistance. Not much else to say really, if you want to get serious on grip strength look no further. These are the best on the market.

Just received them yesterday happy for having them delivered so quickly. Looks like a decent product, will try it out in the coming weeks. However, what are these rust leaks situated at the spot where the torsion spring and handles meet?

Excellent grippers! Recommend

La textura es áspera y no se resbala. El único problema puede ser el tiempo, pero es entendible cuando vienen de importación

I normally wouldn't be interested in hand grips as every one that I've seen is made of rubber or cheap plastic and usually have no grip either. But I saw these were metal and actually had knurling. The same exact kind you would find on the bars at the gym which is really cool. The metal is pretty durable so far though time will tell how well it holds up. They feel very sturdy and premium. Which is always nice. What I particularly love is the grip. It's very detailed and feels exactly like a barbell which is what I wanted. Every time I use it at work it feels like I'm back at the gym. Doesn't slip. Feels great. I do forearm exercises at the gym but I wanted something I could use outside the gym that was portable so I could make use of my downtime. This alone won't blow up your forearms. You'll need to also do wrist curls with a dumbbell. This is more for grip strength training only. If you are like me and deadlift without straps you need to make sure your grip is on point. This definitely helps.

I love this product....!
