Product Description

Captains of Crush The Gold Standard of Grippers

If you don’t have any grip training equipment, chances are your hand strength is less than it should be, and if your grip training equipment looks like a toy that could have come in a box of cereal, the same thing is true.

Captains of Crush (CoC) grippers changed the world by taking what had been a cheap, imported plaything and turning it into a beautifully crafted training tool for serious strength athletes. Made in the USA and known worldwide, nothing else puts power in the palm of your hand like a Captains of Crush gripper.

This is the gripper that changed the world, replacing plastic playthings with something suitable for serious strength athletes, IronMind’s focus since 1988.	Custom Fit for Your Needs The world’s leading hand strengthener, IronMind’s Captains of Crush grippers come in 11 strengths, allowing for progressive training, from rank beginner to someone who can literally crush a raw potato in his bare hands.	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.

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.

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

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.

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.

Size: 5. No. 1 (140 lb.)Verified Purchase

I bought this to build my grip strength and just to get a relative measure of grip strength from day to day and I’ve really enjoyed it so far. I researched several grippers and what stood out to me about this one was its simplicity and the quality and durability of the materials. I have no fear of this breaking or inconsistency in its resistance force. The knurling doesn’t hurt my hands at all, I don’t find it overly heavy, and I don’t mind the slight squeaking noise it makes during use. The shape and size makes it easy to store too. I keep it by my desk and use it every day and have already noticed an improvement in my grip strength. I think it’s fairly priced considering I’ll be using this for a while until I’m ready to move up to the next level. I think the design and look is also very appealing as well. Overall I’m very happy with this purchase and plan to buy a level 2 version in the future when I’ve worked up to it.

Lost my grippers throughout the years. Recently been back into the gym and noticed my grip strength isn't what it used to be. I am very happy with this purchase. The material quality is phenomenal and very sturdy. I keep this in my desk at work and use it daily. Easy gripper for all areas of strength to build strength and stamina.

For all those "used-to-be" gym rats (like myself) who never trained on grippers before, this is a great addition to that renewed workout schedule. Doubtless you're like many others who've used the grippers of yesteryear, with the colored plastic handles. They serve a purpose and can set the stage for these Captains of Crush Hand Grippers.

After reading the reviews and attempting to judge which set to purchase, I decided on the No. 1 grippers. For those eager to gain that powerful handshake, these grippers are an excellent choice. There are guys out there who live to crush the hands of others in a hand shake. One buddy of mine does it all the time..his hands are rough like boiled leather due to working outside all the time. His grip is amazing for a smaller guy, and he has no trouble reaching into a pot of boiling water to take something out. I'd say his grip is a match for mine or perhaps a bit better.

Aside from that, there's only been a time or two when someone's handshake felt like a true heavy-duty vise grip. It's those that I'll never forget, since they were so overwhelming. That's the grip I want.

**Note: the shipping time on these was AMAZING! Ordered Tuesday night after 8pm and was told to expect shipping time of 3 to 5 business days. To my surprise, they arrived in the mail that Friday. I was blown away, because I didn't expect them till the following Wednesday. Kudos to Amazon and IronMind!**

When the box arrived, it contained the gripper set, a short instruction manual, the order/receipt and a cool IronMind catalog [like 50pgs]. I'm sure glad I didn't order the No. 1.5 or 2.0. These grippers are NOT EASY! Since I don't have a set of warm-up grippers [as recommended in the above-mentioned literature], I was slightly concerned. They were not lying when they said most guys at the gym cannot close these. I'd bet it's quite true.

**Recommend adding the Starter or Trainer as a warm up gripper**

Not knowing what to expect, I gave it the old college try. My first set was less than stellar. I failed to fully close the grippers with either hand. The diamond grips on the handles are excellent and by the 2nd set my hands had that strength "memory" back [to some degree]. I was able to close the grips completely 3x with the right hand and 2x with the left..and did a total of 6 reps for each hand.

Due to my inexperience, I waited about 20mins between sets, not wanting to accidentally injure myself..especially so soon after trying. By the third set, I was ready again and was able to close the grips 2x with the right hand and nearly 2x for the left [about 1/4in open]. Remaining reps were judged as "less than manly", with accompanying facial contortions, spastic arm raises and guttural noises.

**Note: I am mixing the conventional and upside-down grip methods**

Since this is my first week with the grips, I'm taking IronMind's advice and only doing sets 3x per week. If all goes well, I should be ready to increase sets and reps after 2-3 weeks. At that rate, I should be very comfortable with these -- and ready to move up to No. 1.5 in two months. My first main goal is to conquer the No. 2 gripper.

In my estimation, these gripper levels are much like hurricanes or earthquakes..as you graduate to the next level, your grip strength rises geometrically. For example, a Category 2 hurricane requires 10x the strength as a Cat1..so by the time you reach Cat5 [155mph+], it requires 10,000x the power required to create a wind speed 2x faster than at Cat1[70mph+]. It may not be quite the same for the grippers, but it sounds good.

Superior quality with a dab of squeaky.

Reviewed in the United States on August 16, 2023

Size: 3. Trainer (100 lb)Verified Purchase

Easy to use?
Have you ever peeled a banana in the dark? My first question to you is why? In the regular grip it fits comfortably, but I can see why some people may be turned off since these aren't made for soft hands. The metal is easy to grip, and grips your skin all the same. I personally like it, but I can understand why some people might not dig it. Reverse (180) grip is actually super comfortable, and probably the only gripper that I can say that about.

Durability?
Ooooooffffff..... First, these are super solid. If I ever needed a makeshift grappling hook, then this would be my hand grippers of choice. My ONE! ONE! ONE!!! irk was that the metal slowly separates from the springs "tang" and has a slightly more audible squeak versus other grippers. Makes it sound like I'm rocking the bed, but since I'm single, that makes a bit more weirder.

Quality?
Quality.

Overall?
These are solid man. Besides my minor little issue with them, I'm definitely buying more as I move up in my grip routine. I don't see any reason why you wouldn't buy these.

Best Grippers, Period.

Reviewed in Canada on April 24, 2024

Size: 7. No. 2 (195 lb)Verified Purchase

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
