I just blasted my forearms yesterday and they have never been so beat up ever.. I started of trying to do one-arm hangs and that didnt work because I couldnt hold more than maybe 5 seconds!!
Ridiculous I know. I did two arm hangs though for maybe 60 seconds... I did 5 sets of two arm hangs which really burnt out my forearms really well.. then I moved onto a giant set consisting of seated bb wrist curls, reverse wrist roller, db twsits, and finished with pinching plates. That totally MURDERED my forearms!!
Monstar-when I first tried one-arm hangs, I couldn't even support my bodyweight.I had to use the two arm version for a few weeks to build up.Like I said, they are a very humbling exercise.Good job just the same.
