I've achieved 100lbs on each arm for so many exercises, all pull, and yet on a few only 50 each arm, specifically overhead, side pull down, and shoulder exercises. So that's where I'm concentrated. To give a sense of how far I've come, when I first did side lateral rise last fall, it was 10lbs per hand, now I can comfortably do full nice form with 35 and beast mode 50
For triceps, I was at 60lbs in February and now I have good form at 100 each but it really strains the wrists so I'm working wrists, I'm up to 40 on the wind up thing I made and switching to 50 soon. I bet I could do 50, so I'll try.
I also got a hand strength trainer, got 125lb grip strength on the scale tester.
