I don't see how I do plenty of forearm workouts such as wrist curls on a bench, rolling the little rope up with the weight hanging on the end, and some other stuff. It could be me squeezing on the bar to hard, I squeeze when I bench and curl and I can tell because my hands get pretty blistered up. I don't know what you mean by uneven pressure on the forearms.
By the way can I get an invite to the lifting cult?
