IronMind Two-Way Captains of Crush Grip Strengthener Set: CoC Trainer Gripper (100 lb.) and Expand-Your-Hand Bands

I've had this for 2 weeks and it's helped to improve my hand strength already. I've been dealing with hand pain for years and since regularly using the grip trainer and the lowest level bands it has improved significantly. My hope is as I progress and continue to use this the pains gone all together. Awesome purchase! You don't realize how week your grip is until you try these out.

Life is easier if you have great grip strength. I keep these on my desk so I can sneak in reps a few times a week. It is really satisfying to work your way up through the numbered CoC Grippers but if you could only have one of them, it is hard to the Trainer.

I'm really impressed with the build quality of both the gripper and bands. I gave one set of bands to my wife and one for me for use at work to get the blood flowing when working in front of the computer. Our hands feel way less stiff and overall more healthy.The CoC Trainer is great for people to start of with. I got myself the CoC trainer, #1 and #2, it's great working out with them. For anyone interested in buying the gripper remember to treat it like any other gym equipment and train with it after a good warmup and have a set number of reps and series.

I bought these after I tried them from my friend. It works great so I had to order my own.

Aside from that, an amazing tool that built my stubborn forearms very quickly

No complaints, the products work exactly as intended and was shipped in perfect condition.I was surprised at the difficulty of the trainer gripper so I would agree with CoC's recommendation to not underestimate the grippers. At 150 lbs bodyweight I can hang from a bar on one arm with an additional 50+ pounds of weight and have never needed straps while dead-lifting. I was surprised to find the trainer is pretty darn difficult to close. I can get it, but my grip is gassed after 3 reps. Needless to say, my ego got a well-deserved check and my advice to readers is don't overestimate yourself like I did.

Stronger grip is a great thing. It helps with all lifting, means you’ll never get your handshake crushed by obnoxious 1980s businessmen, and makes your forearms all vascular. I’m working my way up the ladder, these are seriously tough.I love the expand your hand bands too, it’s a great way to balance out the movements. These feel like they’ve helped my carpal tunnel / tendinitis symptoms too. I spend a lot of time on the computer or playing music and having healthier hands is a huge plus.All in all, highly recommended!

I've tried a few different hand exercisers over the last couple of years. The first ones were the Gripmaster Exercisers, which did not seem to give the improvement I'd hoped for. The next thing I tried was the Dynaflex Gyroscopic exerciser. While that did wonders for helping resolve tennis elbow issues I'd developed (along with the Thera-Band flexbars), it still didn't seem to do much to improve my actual hand strength.The CoC Trainer, however, has been giving some very noticeable results over just the last month. While I could easily close a Heavy Tension Gripmaster, I initially could only get the CoC Trainer about halfway closed. But I am now able to manage it about four times in a row. These can be quite humbling. But they are effective.
