Hey guys, just wondering if any of you have had any experience with the "Captain of Crush" series of hand grippers to improve grip strength? They are made by "Iron Minds" and here is a Wikipedia link to them describing them... Captains of Crush Grippers - Wikipedia, the free encyclopedia. I purchased the Trainer & the #1 to start with and not long after (3 mos.) I purchased the #1.5 & #2. I think they work awesome and are very well crafted and they have helped me increase the Lbs I'm able to lift or should I say pull in my back exercises, especially dead lifts, without the use of straps! Anyway, I think they are awesome, just wanted to see if anyone else out there had an opinion?
