## Description

desertcart.com : Captains of Crush Hand Gripper - No. 1 : Sports & Outdoors

Review: Crush your opposition! - 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!
Review: Just starting out, but very excited - I'm pretty new to grip training. In the past I had gotten some other grip trainers and developed a semi-regular habit for a little while, but it felt like I wasn't really getting anything out of it. Well, I see why now lol. I'd gone for lower-end products, like what you could find at most stores. The adjustable ones I thought at the time were nice, the ability to work up, but if you're a guy with decent passive strength (not a bodybuilder or rockclimber, just a regular dude) you'll probably find yourself mastering that relatively quickly and just sort of getting bored and forgetting about them (much like myself). With these I'm reminded that there's a reason good things may cost a little more or be harder to find. I started with a #1, and that's a good spot for me currently. They recommend starting a little lower, but I like having a bit of a challenge on the front end. I think I chose well. I could close them, but it's not easy, you know? And that difficulty makes me more excited about using them. I'd rather struggle to get to like 5 than be able to blast out 50 without feeling any burn. Then after a while, the comfort in doing more reps will feel earned. And I really don't mind that these aren't adjustable nor that they're sold as singles. You can buy two I suppose, (I always used to think you needed a pair?) but really I think if you're double fisting, you might just need to go up a level and focus on one hand a time. As for adjustability, I think their numbered system of individual weights works better. Even if it's somewhat of a marketing thing (maybe but not really), I like the idea of having a solid and well built product that is 100% the weight it states, and once you become comfortable with that, that's that. And I'm excited to make that next step up. Also, to be clear, I'm not just saying they're tough. They're of very good quality as well. You know that annoying squeaky/clinky sound cheap that cheap grip trainers make when you're going to town on them? I don't! Not anymore lol. This is a solid product. No plastic components, no foam tube that slides off, no tiny tin plate that slides around as you close them, no squeaky-squeaky, no wondering if you should duct tape the handles for your hand's sake. It's a nice, weighty metal feeling, and the handle has a nice texture that neither slips nor hurts your hands. So positive all around if you couldn't tell. And one day I will ascend to bigger numbers.

## Questions & Answers

**Q: I am looking to increase my grip, as my grip fails at 225 on deadlifts?  Shoukd I start with trainer or #1?**
A: Dear Darren:We recommend that you start with the Captains of Crush Trainer. When you can close it for 10-12 full, legitimate reps, you can start to work on the Captains of Crush No. 1 as well.  Thank you for your interest in IronMind equipment and best of luck with your training!

**Q: Does ordering from Ironmind on Amazon include the coc setting card?**
A: Dear Sir/Madam:

Many thanks for your inquiry.  The Captains of Crush ID card is not included with Amazon CoC gripper purchases.  If you would like an ID card after purchasing a CoC gripper on Amazon, kindly send us an e-mail with your mailing address and a copy of your Amazon order and we will be happy to provide a complimentary CoC ID card.

Thank you again; we appreciate your interest in IronMind equipment!

Sincerely,

Judy Mariuz

**Q: I have Walmart medium strength grippers. I do them ok  I want to move up but not so much that I can't do themWhat Strength COC gripper would suit me?**
A: I have those walmart ones and they are easy. If you can do a set of 12 it is time to order the CoC "Guide". I would say they are a little tougher than the walmart ones. I read the walmart ones are 50lb and the CoC Guide is 60lbs so that seems right. Great quality. Or get to where you can do 3 sets of 20 with what you have and get the 80's.

**Q: Best no to start with**
A: For an adult, normally if a person is ready for serious grip strength training but has not specifically trained with even a plastic-handled sporting goods store hand gripper or done any crushing work, we recommend that they start with the No. 1250 Captains of Crush Trainer gripper, or a No. 1402 CoC Sport gripper. If you have been working with sporting goods store grippers and have worked up into high reps, or if you use your hands daily in a stressful physical task, like construction work, then we recommend starting with the No. 1251 Captains of Crush No. 1 gripper.  Please let us know if you have any further questions!

### ⭐⭐⭐⭐⭐ Super high quality, better have a vice grip if you plan on making regular use of these...
*by T***O on February 24, 2015*

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...
