Which is harder for people with big hands? I have big hands and so the bars, barbells, and dumbbells at my gym take little to no effort to grip securely, so I never get a good forearm workout. Consequently my forearms are pretty skinny.
I've looked at the grip4orce videos, and it doesn't seem that hard to close one or keep the opening pointing into the palm of hand for a person with big hands. FatGripz are thicker, perhaps that is better?
Anyway, for people with big hands, which (Grip4Orce or FatGripz) would give a better grip/forearm workout?
