So i have these steel grippers that i used to train forearms with twice a week. I have like 5 of them. 150 pounds, 200 pounds, 250, 300, 350
This is noname brand so the weight nr is not correct probably but it is irrelavent. I stopped using them like almost a year ago because i developed this pain in near the knuckle on one finger that was really annoying.
Last time I used them, i could close the 300 pound one, on a good day, with right hand 5x and with left 1-2 maybe. ANd on a bad day i couldnt close it at all with left and barely could close it with right. And that is with warmup using the weaker grippers and chalk.
I just moved so i found the grippers again and i took the 300 pounder and i can close it with ease for reps now with both hands(no warmup no nothing). I can even half close the 350 now what wouldnt budge at all before.
So i must say im very positively surprised. I guess gym training has some carryover to crush grip also. Ive been hitting wrist curls alot last 6 months or so also atleast maybe that contributed
