IronMind LogoIronMind Logo

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.

So, if you’re serious about having stronger hands—whether you are a senior citizen or a SEAL—pick the best tools you can get your hands on, starting with Captains of Crush grippers.

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

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.

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

IronMind Grip Strength for GolfIronMind 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 ShootersIronMind 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 CourseIronMind 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.


Original, authentic, unmatched—the gold standard for building and testing grip strength. Designed to produce the quickest gains in grip strength.

For strength and conditioning. Silky smooth handles and a smooth ride for high-rep training, a perfect complement to CoC training.

Most people who train with grippers think they feel fine in both hands, but if you think your left hand has gotten short shrift, meet Left-Turn grippers.

Train one or two fingers at a time, including your thumb. Tune up your weak fingers, advance on CoCs, power up your pinch grip. IMTUG is your best friend.
