hey,
I registered just bc I was reading this. I use an "EZ" bar and put a plate on each side (135 lbs) and I hold it behind my back and curl it upward and i'm definitly starting to notice definition in my forearms and wrist, you can also do reg. forearm curls. The thing is, you use your fourarms everyday for whatever, whether it be lifting or working with a wrench, or at another job you might have, so your already toning it. thats why i like to do high weight low reps when it comes to forearms, yet I still do anywhere from 5-8 reps and sets.
