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

Reviewed after three weeks use. They accidentally sent me the #.5 120lb grippers instead of the Trainer (it was packaged right as the .5, but the SKU sticker was for the Trainer). I figured what the heck, 20 more lbs would probably be a good place to start anyway (and I was really excited to get started training). Shoot dang, these are some TOUGH grippers. Firstly, just to echo what other reviews say, these are well-built, durable grippers - the finest I've ever owned. If you're combing reviews for competing products, there just isn't much out there that compares. Secondly, there is a serious difference between the repetition training that your sport shop grippers offer and the intense high-resistance training you can get from these grippers. I've seen a bigger difference in three weeks of these grippers (with focused effort) than months of reps (mostly while watching tv) with the others. If you're looking for more than muscle maintenance, and serious about being able to effortlessly open that jar of pickles when your girl is there watching, low-rep high-intensity is the way to build grip strength. I still can't close the 120lb beast, but I'm a lot closer, and am already getting some noticeable forearm definition. If I might offer a few suggestions to get the most from these grippers: - Gripper training is an isolation workout, meaning you're targeting just one specific motion/muscle set. In this case you are targeting your crush grip strength. For well-balanced strength, you should also train your pinch and support grips. Read up on how to do all three in balance. It will amaze you how much they work together, and you'll see much faster gains than just periodically working the gripper (think especially about how your pinkie and ring finger will help so much more if they have some pinch strength to them). Ironminds also offers all kinds of elastic bands and pinch springs to complete a workout. I personally have a medium tension Gripmaster from prohands and feel that starting exercises with that works out a lot of finger and joint kinks before getting down to business with the gripper. If you're cracking every joint with the first crush, you're not warmed up. - You'll want some focus, these aren't the carry-in-your-car type of grippers. Not that they couldn't be used that way, but taking time to properly set the grippers and using focus strength will get you a better workout. I usually do my gripmaster warmup on the drive home, and then do my reps when I walk in the door. I feel this optimizes the workout routine, and gets more bang for less time. - Do more than just the standard close routine. If you look at the IronMinds instruction booklet (doesn't come in the package, but you can get a free one from the IronMinds store), you can find an array of different workouts that you can do with one set of grippers. I usually do a few reps spring up, spring down, and then burn out with some negatives (starting with a closed grip) for a full workout. It takes a little while longer, but it really gets ALL the arm muscles burning, and really pays off. I'm still working hard at trying to close the #.5, and am already making plans to start stepping up. I might also get the Sport just for warmups, the #.5 is too much to warm up on. I would recommend these grippers, and look forward to having that quiet strength grip. If you meet me there, I'd be glad to shake your hand!

I just bought these based on Pavel Tsatsouline's recommendation for strength training, and let me tell you: I am impressed! These things are SOLID! I'm talkin' aircraft-grade aluminum. The trainer model is 100lb of pressure, which is roughly equivalent to being "pretty effin' hard to squeeze" for the average person. You can quote me on that. An interesting thing I learned behind this training methodology is the theory of neural recruitment, IE, after trying to fire that particular pathway, the nervous system adapts and is able to recruit more muscles and fibers to do the job. Sounds like HUH? But no, really, guys, it works. When I got these out of the package I could just barely squeeze them twice without busting an artery. In four hours of squeezing approximately one time every twenty minutes, I was able to do 4 with each hand. The next day, I could do 8. Now, don't get me wrong - that was painful, so, I'm not about to try and set any world records, but I doubt very much my hands got FOUR TIMES stronger in 48 hours. So there must something to that whole neurology science... A note about the grip: the aluminum is micro-studded to create a coarse surface for enhanced grip. In all honesty, it's kind of rough. If you don't have callused palms, wear a glove for the first couple of times you use these, otherwise it might be downright painful. I'm no hand model, either, and have moderate calluses from the pull-up bar and kettle bells on my hands, and these grippers gave my palms a beating. It's something you get used to, without a doubt, and would probably help toughen up the hands, too, but I'd be worried about tearing up my hands when going up in tension to 150lbs and above. Speaking of which - you can clearly see the line dividing the gripper handles in half in the picture: top and bottom. That effectively makes it 2 sets of grippers, the top one being much harder than the other (at least 30%). By orienting your grip more on the bottom half, you get less resistance and more travel. Top half - more resistance, less travel, respectively. So if you have freakin' gorilla hands and get these and are like "pfft, I can squeeze these with my eyeballs", first of all - props, and second of all - try getting closer to the spring, you man-ape-gone-wrong-thing. Good luck and don't forget the lotion after. I won't be buying a tighter one for a while...

get a trainer or 40kg gripper from them before attempting this if you want insane handshake

Best grippers on the market. The captains of crush are the quintessential grip training tool for anyone that is serious about improving grip/hand/forearm strength. Forget about the plastic spring one from your local department store, this is the real deal. The #2 is not a beginner gripper and is challenging to close. If you are starting consider a trainer from captains of crush or a half size like a 0.5. These grippers get better with time and will last forever, very sturdy build and can take anything you can throw at it. Pricey but worth every penny

El producto es tal cual se vende y promete. Muy resistente,dureza y el metal de primera.

Miles de repeticiones y sigue intacto, es un gran equipo para lograr fuerza y masa en los antebrazos.

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.
