These do work if used regularly. I got them mostly for climbing and my hands and forearms are taking a lot longer to tire on the wall after a couple months use. Blue was actually quite hard at first, I was struggling to open them all the way even one time but in a month or so i was able to do sets of 15, no prob. Im happy with the results so far.
Im a figety person so these things have been great for me. I end up using them all the time. They will make your arms burn like nothing else, for real. My arms look way more burly after a few months. I recommended them to a few friends who use them now too. One has had tendonitis on and off for awhile and he says its basically gone now. So I figured I owed it to you to answer your review request. Great little product. Thanks.
I bought for myself and a friend. Both of us lift and these have been a nice addition to ad in at the end of our workout for burning out the forearms and have worked surprisingly well. They defiinitely hit the extensors and stabilizer muscles on the back of forearms that is unique. I was not expecting them to give me the pump that they do! Way more than I expected. Thanks and would recommend.
I have gotten a lot use out of your gripz. I work in a call center and use them at work all day while Im on the phone, nothing else to do so i end up fiddling with them all day and Im happy they work so good. I can definitely see more definition in my forearms now. Took a little while but they work and are very convenient for me so Im happy and will recommend. Thanks!
