Product Description

Made in the USA and known worldwide, nothing else puts power in the palm of your hand like a Captains of Crush gripper.

Top Quality and Affordable

With legendary build quality and proprietary features, Captains of Crush (CoC) grippers are in a class by themselves, and while you might not have the budget for a world-class car or truck, CoC grippers are affordable so you can get a top-drawer training tool, instead of a piece of mass-produced junk.

First Family of Grip Strength

Captains of Crush (CoC) grippers are part of the CoC Compatible (CoC²) of hand strengthening and hand health products developed by IronMind, the industry leader, Grip Central since 1988.

IronMind Captains of Crush Grip Strength - CoC No.1, No.2, No. 3

Where to Start

  • If you are a beginner, a senior or a rehab patient, the Guide might be perfect for you.
  • If you are active, but have not been training your grip and your job does not involve hand strength, then the Sport is the most likely place to start.
  • If you have been doing serious overall strength training, but have not specifically trained your grip, start with the Trainer.
  • If you use the strength of your hands in your job or if you have been training with sporting-goods-store-type hand grippers, start with the No. 1.

Just to keep this in perspective, most people who lift weights cannot close a Captains of Crush No. 1 gripper the first time they try and only rarely do we ever see someone close a Captains of Crush No. 2 gripper on his first attempt.

IronMind Grip Strength for Baseball

Grip Training for Baseball

Whether hitting, pitching or throwing, increased wrist and grip strength are key to playing better baseball.

  • Hitting: Gain control, boost bat speed, and add the horsepower you need to hit those long balls
  • Pitching and throwing: to increase velocity, accuracy, stamina and protection from injuries, make a balanced grip training program a regular part of your workout
IronMind Grip Strength for Golf

Grip Training for Golfers

A strong grip is essential to golf. Pros tend to have greater maximum grip strength than amateurs and—somewhat paradoxically—stronger hands allow you to have a more relaxed grip while maintaining head control and consistent body mechanics.

IronMind Grip Strength for Shooters

Grip Training for Shooters

Your thumb is important in shooting, but when it comes to controlling a handgun, it’s secondary to your other four fingers, so your focus is on what’s called crushing grip (think shaking hands and squeezing). Captains of Crush grippers are your first choice for increasing your crushing grip and they will be the cornerstone of your training.

IronMind Grip Strength for Obstacle Course

Grip Training for OCR and Climbers

Hand strength is key for obstacle course racers (OCR) and climbers, and most of the grip-related challenges you will face will depend upon the strength and endurance of your crushing grip. Captains of Crush grippers are the fastest route to a stronger crushing grip.

I got my first two grippers, the Trainer and the 0.5 back in 2018 and I've trained just with those two for years, until a few months ago I decided it was time to take another step in my gripping journey and decided to get the # 1. It arrived today during the afternoon and fresh out of the package, I was able to do 5 reps with no issues (plus a couple more for the pictures I took for this review. It's very hard to take a picture of a close while trying to show the bottom of the gripper in good focus!).The build quality is just solid, easily the best grippers I've tried and owned over the years. The bump from the 0.5 to # 1 also feels right. Not too hard if you've been training regularly, but just hard enough to make you work for the next jump, the # 1.5.I put my old grippers, the Trainer and the 0.5, next to the fresh # 1 to show how my old ones have held up. You can see that the old springs have lost their shine and they've developed a little bit of rust where the spring makes it into the handles, but all of this is my fault as I've gotten lazy over time at giving them maintenance. But these are super easy to keep nice and shiny if you wanted to (and you should), and even after all these years, they feel great to close.

As someone who’s serious about strength training, the Captains of Crush Hand Grippers have become an essential part of my routine. I’ve purchased the Trainer (100 lbs), 0.5 (120 lbs), No. 1 (140 lbs), and No. 3 (322.5 lbs), and they’ve proven to be the standard for grip strength development at every level.Build QualityThe craftsmanship on these grippers is unmatched. The knurled aluminum handles provide a secure grip, even during intense workouts, and the spring mechanism is built to last. These feel indestructible and are clearly designed for people who are serious about increasing their grip strength.Progression and ChallengeEach gripper offers a unique challenge:Trainer (100 lbs): Perfect for beginners or as a warm-up tool for advanced users. It’s a great starting point to build confidence and form. However if you already have a strong grip you may want to pass this one for the 0.5.0.5 (120 lbs): A slight step up from the Trainer. It bridges the gap between beginner and intermediate levels, making it a staple for building grip endurance and strength. If you struggle with the No. 1, but find normal grippers easy this is a great option.No. 1 (140 lbs): A true benchmark for serious lifters. After many, many, many failed attempts, closing this for the first time felt like a significant milestone. In fact I've still not managed to close it with my left hand, and it may be several months before I get to that level.No. 3 (322.5 lbs): I foolishly purchased this years ago thinking my grip was above average. I can't even close this bad boy with 2 hands yet. However while I haven’t closed it yet, it serves as a motivating goal and still offers a lot just from the attempts. However if you haven't closed the 2 or 2.5 I would recommend you pass on this one.My ExperienceI became interested in grip when it started becoming a limiting factor in my deadlift before I finally adopted straps. I still incorporate these grippers into my routine 2–3 times a week, using the lighter ones for warm-ups and endurance training, while pushing my limits with the heavier grippers. Now that I've finally closed the No. 1, I plan to master it before progressing to the No. 1.5 and eventually the No. 2. It's also a lot of fun to see friends and family attempt them for the first time!Who It’s ForWhether you’re a beginner, an intermediate lifter, or a seasoned athlete, Captains of Crush has a gripper for you. The progression system allows you to scale up as your strength improves, and the quality ensures these tools will last for years.Final ThoughtsCaptains of Crush Hand Grippers are more than just a training tool—they’re a benchmark for grip strength enthusiasts. You can even check their website for the leaderboard of people who have closed them in competition. If you’re serious about improving your grip, these are a must-have. Just be prepared to work hard and feel incredibly rewarded when you crush your goals.

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.

I regret not reading more into the descriptions as I ended up getting the Guide as my first gripper which I've already got most out it in a matter of weeks. My hands and forearms feel stronger but I overestimated myself because I ended up order the No. 1 next which I could barely close half way with my dominant hand. These work great but I now know I should have started with the Trainer or atleast the Sport.

i più famosi, i più ambiti, i più leggendari."quando vi arriveranno e finalmente vi troverete faccia a faccia con questi gripper, aspettate ad aprirli, lasciateli nella custodia ed osservateli, contemplateli, ammirateli, tributate loro il rispetto che meritano, poi, quando vi sentirete degni di poterli impugnare, toglieteli con cura dalla custodia, stringeteli bene nella mano e iniziate questo viaggio verso la gloria."ahah, apparte queste fantasie, semplicemente se siete degli appassionati di allenamento della presa non potete non avere questi gripper, dovete assolutamente possederli.DESCRIZIONE:ragazzi, qui stiamo parlando degli unici ed inimitabili gripper di riferimento per testare il proprio livello di forza della presa.chiudere queste pinze è il test di forza per eccellenza, ovunque nel mondo il vostro valore come atleti di questa disciplina verrà giudicato in base al numero del COC che riuscirete a chiudere, tutto il resto non conta, sono solo chiacchere e distintivo, se vorrete dimostrare a tutti quanto siete forti dovrete farlo usando i COC.certamente esistono tante altre marche di gripper di qualità altrettanto alta se non addirittura superiore a questi COC, ma di nuovo resta il fatto che questi gripper sono gli unici ad essersi affermati fin dagli albori della disciplina del grip e bend come i gripper di riferimento da utilizzare per definire il vostro livello di forza della presa.a nessuno interessa che numero di HG o GHP riuscite a chiudere, l' unica cosa che conta è quale numero di COC riuscite a chiudere.chiudete un COC 2 e siete forti, chiudete un COC 2.5 e siete molto forti, chiudete un COC 3 e siete degli atleti d elite di livello mondiale, chiudete un COC 3.5 e siete dei CAMPIONI, dei veri e propri MOSTRI, chiudete un COC4 e siete delle divinità, delle leggende immortali il cui nome verrà scolpito nella pietra e onorato nei secoli da tutti i praticanti di allenamento della presa.a questo punto però mi sento in dovere di chiarire una cosa:il fatto è che se non vi interessa il discorso di confrontarvi con altri atleti e non sognate di poter entrare nell' olimpo dei grandi che sono riusciti a chiudere il mitico gripper COC 3, dal momento che queste pinze sono molto costose vi consiglio eventualmente di guardare anche altre marche più economiche che comunque vi permettono di allenare in modo molto soddisfacente ed efficace la vostra presa.chiarito questo punto, parliamo adesso delle caratteristiche tecniche di questi gripper.CARATTERISTICHE TECNICHEla zigrinatura è eccezionale, davvero ben fatta. il discorso è che offre un grande attrito e quindi la presa sarà ben salda sui manici ed il gripper non tenderà a scivolare ma al tempo stesso, la zigrinatura non è assolutamente "traumatica" per la pelle, cioè non taglia e non graffia quindi è confortevole da usare.la distanza dai manici è molto elevata, si parla di circa 7.2 cm (misura effettuata con un calibro), infatti dovrete per forza di cose dedicarvi ad una preliminare fase di setting del gripper nella mano prima di poter procedere alla chiusura.questa cosa è abbastanza frustrante se avete le mani piccole.una soluzione potrebbe essere applicare una fascetta stringitubo sull' estremità superiore dei manici cosi da andare a ridurre l' apertura di partenza, però a lungo andare rischiate che a lungo andare la molla vada ad allentarsi facendo in questo modo perchè non sarà mai a riposo e rimarrà sempre sotto tensione.altrimenti, se la distanza elevata dei manici è un problema, ci sono sempre altre marche di gripper che hanno una distanza di partenza inferiore e questo vi consente di allenarvi senza lo stress del setting, per esempio gli HG hanno un' apertura di circa 5.5 cm e costano anche la metà dei COC, potrebbero essere una buona soluzione.a parità di libbre dichiarate, i COC sono molto più duri rispetto ad altri marchi.per intenderci, un COC 1 che corrisponde a 140lb è in realtà duro allo stesso modo se non addirittura di più rispetto ad un HG200 da 200 lb.quindi non sottovalutate assolutamente la durezza di questi gripper, già un COC 1 sarà impegnativo da chiudere e richiederà già un buon livello di forza. qui si gioca duro!il diametro dei manici è di 19 mmil numero che indica la durezza della molla è riportato sul fondo dei manici.CONCLUSIONI:concludendo il discorso, diciamo che:se volete mettervi alla prova confrontandovi con altri atleti provenienti da tutti gli angoli del mondo, dovete comprarli, almeno il numero 1, 2 e 3.se invece vi interessa solo avere dei buoni gripper con i quali allenare la vostra presa, sicuramente questi sono gripper validi ma sono anche molto costosi e oltre al nome e alla durezza delle molle che come dicevo sono calibrate per essere usate come metro di riferimento "ufficiale" per la forza, non hanno nulla di speciale rispetto ad altri brand, quindi potete benissimo orientarvi su altre marche più economiche che fanno lo stesso identico lavoro di questi gripper ma costano di meno.ciao

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
