Overview:
Captains of Crush classic hand grippers have been specially designed to enable you to gain maximum grip strength in the shortest amount of time.
Irrespective of your application, there is a high chance that CoC is going to work well or be a good fit for you. Just give it a little squeeze. It’s my favorite grip training tool. It’s a straightforward & effective way to develop the overall grip strength.
This is not a plaything. It’s a professional training tool that will damage your palms in no time for them to be stronger. This equipment will improve two skills of grip strength – Crush grip strength & Static support grip strength. The first one is used for crushing objects by squeezing them with your fingers and the second one is for static grip to hold heavy stuff.
Whether you are a weight lifter, rock climber, wrestler, or motocross rider, you need a strong grip to be on top of your game.
The gold standard is Captains of Crush & this is its legendary construction. It’s made of aero-grade billet aluminum & alloy steel construction which makes it super powerful. Produced by IronMind, an established brand since 1988.
The manufacturer provides their famous spring gripper with a one-year warranty, just in case you happen to break one.

Cons:
- Designed for Right Hand – This is a model that will work on your right hand initially and only after that your left hand. In the meantime, this helps in strengthening both hands’ muscles with different sensations when you train the left hand. In most cases, it’s a minor detail that most folks just won’t know: If you seek maximum comfort, performance, and precision for left-hand training, then the combination of CoC Left-Turn and a standard CoC gripper is optimal to use.
- One Resistance Level Per Gripper—Unlike adjustable hand grippers, CoC is a stationary one of resistance levels per type of gripper level. If you want to add strength & maximize the progression of your training & have more fun, you probably have to invest more in you’re side in order to get grippers with different resistances.

Any Athlete, Men & Women, Older & Younger

Your age doesn’t matter, nor does your gender (young or old, male or female), trainee or recreational athlete – grip training will supplement your functional strength every single day. In fact, the first contact of the majority of sports with an object is with the aid of your fingertips. Doesn’t matter if you’re playing basketball, baseball, golf, or weightlifting- you will definitely use either a basketball, baseball bat, golf club, or weightlifting barbell.
The higher the muscle strength of your hand will be, the greater the chance it will be for your performance in your sport.
Toughen Your Palms With Captains of Crush
Avoid Fitness Gloves
It is not rare to see individuals wearing gloves when they go to the gym and as a result- they usually have weak palms. Gloves are out-of-place and additional elements between your palms and the weights you are lifting. Clearly, the gloves hinder your palms from improving in strength.
As soon as you put on your fitness gloves and lift your first barbell or dumbbells your hands are going to start shredding at the palms. Of course, your hands hurt at the beginning, and eventually, you blister.
Therefore, the question is: How do you solve that problem? No, you don’t have to wear the gloves again. The grips of Captains of Crush turned out to have very deep knurling surfaces that were intended to harden the palms of your hands. Keep your drills and your hands become muscular. Simple. Slowly yet surely, by the time you finish the 4-6 week training with grippers, your palms will turn callous. It provides one of the key conditions in order to be able to perform more intense exercises without using equipment.
Unless your hands already have some serious injuries you have done the most with your hands, think of no more excuses or reasons to use sports gloves. You always tend to avoid fitness glove use & to build functional grip strength you have to work with bare hands.

Why Should You Always Choose a High-Quality Gripper?
Consistency & Precision
It may well be true that after forming a habit of holding for several weeks with your cheap plastic gripper, you may even close it like a champion. It makes you think that you’ve come a long way in a very short time. Have you? And another thing. ..
If you’re a realist you know it’s clear as day that nothing is invulnerable – If you try hard enough, you can break CoC grips as well – That usually happens only when you maintain your equipment poorly: For instance, if you put your grips in too humid conditions, not cleaning your equipment properly or even changing or exercising with the gripper improperly.
1 The thing is that low-quality grippers spring will wear out soon. It keeps getting weaker and weaker.
However, as you progress and get stronger, the gripper’s spring becomes weaker and weaker. In short: They probably are. Inconsistency often includes their geometry: Unbalanced handles, and spring positioning. Small but effective nuances.
2 Another drawback is that cheap gripper springs tend to snap easily. That’s your safety issue.
There is a probability that you may hurt yourself particularly when the spring breaks in the middle of the exercise and you get hit by the shards of broken springs.
When it comes to buying a pair of hand grippers, make sure you invest in a good quality set – they are super consistent & there are so few instances of any equipment failure. Furthermore, there is better precision of the engineering processes so that there are no sudden geometric shapes that may alter your results. You will get the quality plus enjoy the benefits of a professional both in the room workout routines and in eliminating guesswork.

Hi Henry,
At first I thought Oh no this this is going to be hard to make a comment on because it’s not something I would be interested in. I’m not a bodybuilder don’t intend to be. But as I scanned through the information on the page I noticed there is information on uh using the gripper for recovery.
I recently broke my shoulder and am in healing process and will be entering physical therapy next week so it’ll be interesting to see if this kind of tool is employed in the process of healing my shoulder because I’ve noticed that using my hands exercises the muscles in my arms and that is what is going to get my shoulder stronger.
And I also see some great information about why a person shouldn’t wear the exercise gloves all the time hadn’t really ever thought of that i also see some unusual products there like thumb grippers and hand bands.The page is a bit long for my sensibilities. I tend to like sites that are broken up a little bit more. And I think that might be just personal preference because I’ve found that many sites where you have to scroll a lot are sites that are trying to hard sell me on something.
This is not that sort of thing it’s a legitimate product and there is great value in the information that you’re providing about the product. Just a personal preference that you might consider as you look at your navigation on your site. Overall I’m impressed with the product. Who knows during my recovery I might be just coming back to it and clicking on it to buy one.

Being pain free is inherently a goal for most of us. We tend to not think about it, especially when feeling well. However it’s always a vital part to keep our sanity intact. Hence the importance of functional strength.
Muscles don’t have to be large or particularly well defined to be amazing at excelling in their tasks.
I hear you’re going through some potentially life changing hardships. I am curious how working with gripper could personally benefit you rehabilitating severe shoulder injury. Upper & lower arm are directly connected after all, sharing blood vessels & certain nerve clusters that need nursing.
