  • CoC or Grip Genie
Size: 3. Trainer (100 lb)
I bought an 80lb and a 100lb CoC gripper to work on my hands, forearms and biceps from home since I don't have room for much else. That and I don't live near any gyms. These work great and if you use the religiously, you'll see results pretty quickly. When I first started I could only probably close the 100lb consecutively 10 times with my right hand and maybe 5 with my left so I had to work with the 80lb for awhile. Once I got to the point that I could close the 80lb about 60 times consecutively with my right hand, I went back to the 100lb one. Grip Genie had black Friday deals going on so I bought their 150, 200, and 250lb grippers. I can now close the 150lb with right hand about 10-20 times consecutively as well as the same for my left hand. I can also close the 100lb 40 times with my right hand and 20-30 times with my left hand. The key differences between CoC and Grip Genie is that CoC has a silver coil, silver grips and the grips are a tad smoother. Grip Genie has a black coil, the grips are color coded based on what weight they are and the grips are rougher. I prefer Grip Genie since the rougher grip doesn't slip in my hand as well as them being color coded helps with quick identification. CoC is still great though, so they get a 5 star review. A small tip when it comes to grippers would be to always have the next weight up with you while working out. Start with the heavier weight and do as much as you can, even if you can't close it all the way. You'll be able to do a lot more closes when you go back to the lower weight one that you would if you didn't start with the heavy one. Also my forearms have gotten wider than my biceps lol. ... show more

  • Bought the 1, with a current deadlift of 185
Size: 5. No. 1 (140 lb.)
I’m plateauing at 185lbs deadlift due to grip strength and some pain (from the grip area on my palms). I bought this to improve my grip strength. The #1 seems like a good place to start as I can maybe close it 50% on the first day. This level should keep me busy for a while.

  • Grip strength boiii
Size: 6. No. 1.5 (167.5 lb)
I have the Captains of crush trainer (100lbs) all the way to the 1.5 (167.5lbs) so far and i’m almost ready to go up again. Using these daily has seriously increased my grip strength as well as the visible muscle tone in my forearms. The captains of crush trainers are well made and durable enough to be apart of my everyday routine. It’s basically a fidget for an adult. I break it out when sitting in traffic or watching a movie because it’s not only a fitness tool, it’s also genuinely fun to use. ... show more

  • What I wanted from a grip strengthener
Size: 2. Sport (80 lb)
The grip on this is superb, a little rough if you aren't used to anything abrasive. But it doesn't cut in to your skin, and it allows for a good non slipping grip as you use it.
