IRONMINDCaptains of Crush hand grippers (CoC Trainer c. 100 lb 45kg)

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

This is the real deal people - great for building up your wrists and forearms and overall grip.A lot of people on here had warned not to go OTT with the selection. I wanted a warm up gripper to start with my workout, then move on to a stronger resistant one, so decided to go for the T (trainer) and No1. Boy did i make the wrong choice LOL. i am fairly strong but i really struggled with the T (trainer) and now i'm scared to even try the No 1 as I know i'm definately not ready for it yet. I would suggest if you are not used to any resistance in terms of hand grippers, but fairly strong in strength to help kick start your journey (and i don't mean from using those cheap plastic no resistance ones that you can get for peanuts), then go for at least the Ironmind CoC Sport or Guide variant. This will help compliment your T (trainer) until you can fully close it after a few reps of 10 with ease. Oh and by the way, you WILL get sore hands after using this, but it will help build resistance and power in them eventually, so choose wisely.

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

While the price is higher than other grippers, the build quality truly feels great. I've noticed my grip get significantly better using this.

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?

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

High Quality build.
