The gold standard for building and testing grip strength

If it ain't broke don't fix it. CoC's were used by the strength fiends and strongmen of old.  The difference between a weak and a strong grip is the difference in reps, seconds, kilos, and speed. Nearly every measure of performance is affected by your ability to lock on, hold on, and maintain your strength.

Captains of Crush Grippers: Maximum grip strength, minimum time.

Made in the USA.


Forget about the traditional approach to training with grippers - banging out endless reps while driving or watching TV - as it will do little to improve your grip strength but a lot to shorten the life of your gripper.

Captains of Crush Grippers is rated 5.0 out of 5 by 14.
Rated 5 out of 5 by from Great tool I have number 1 and 2. Number 1 has become my gripper to use for reps. If I can close the 2 a few reps am having a decent day. If you are of average strength I would start light with the Sport or Trainer and work up to a 1. Most males cannot close a 1. I would love to be able to do a number 3 someday. The grippers are of very high quality and give your hands a true workout.

Rated 5 out of 5 by from A Necessity I bought the "Trainer" to get started on as I've never done any sort of grip training before. I'm not a weakling by any means, but I do have long spindly fingers and I'm hyper-flexible so not genetically predisposed to having a crushing grip. After following the CoC's grip training protocol for about two weeks my closes went from 6 at the start and a :18 second hold to 24 closes and a :26 second hold. My hands feel so much stronger. I'll be buying a CoC Men's Set next. This is a great product and will definitely translate into your lift totals as well.

Rated 5 out of 5 by from The Real Deal!! I just got my Captains Of Crush (1.5) in last week. I figure it was a good starting point. I was able to complete it in a few days but I REALLY had to work for it. Best thing for strengthening your hands by far. I'd recommend this. In fact I'm ready to move to the #2!!!

Rated 5 out of 5 by from GRIP TIME I first purchased the Trainer gripper to start. At first it was difficult, but after about a week I could do about 15 reps with my weaker hand, and about 20-25 with my stronger hand. I just received the 1, 1.5, and 2. After first opening them i was ablke to close the 1 & 1.5 with both hands, but it was definitely a challenge. These grippers are legit. If you want a badass grip, you have to use these. I'll revise this review in a couple weeks and note my progress with the new grippers. Hard work really pays off with these!

Rated 5 out of 5 by from Great Product I just received the CoC's that I ordered. Got a Sport, Trainer, and 1. Wanted to get a light one, working one, and figured I wouldn't be able to close the 1 yet. The Sport is pretty easy, Trainer is good for me to work on, and I am about 4 mm from closing the 1. Craftsmanship is really quality, nice weight but not heavy. The round handles don't let you cheat and kind of tuck the grip in your palm like some cheaper ones I've had. For strength reference, I lift routinely weights, including wrist curls, and use hand tools to carve wood, so I'd say the 1 and either a Sport or Trainer would be an excellent combo for someone starting out with grippers. Have fun!

Rated 5 out of 5 by from Great & convenient These will definitely increase your grip strength. The knurling is aggressive and allows me to get a better hold. CoC's product description for each gripper helped me make the appropriate decision on which ones to buy.

Rated 5 out of 5 by from I crush you. These are some pretty serious grippers. I have above average hand strength from doing manual labor all my life, swinging sledgehammers etc. so I decided to go with the men's set with the 1, 1.5, and 2 grippers. Im glad I did, I can close the number one probably eight times, and the 1.5 once so its a perfect place to start. The knurling is very aggressive, so if you fold doilies and pet rabbits for a living you may want to wrap the handles in cloth tape. Perfect for toughening your palms though. I would also recommend the expand your hands bands to keep from messing your elbows up.
