How much do those run, Illuminate?
One thing I do is I use the roller method to help build up my forearms. I don't know the name but the rope or strap is attached to some weight and you have the rope hanging down and your handle. You roll the rope all the way onto the handle and then take it back down. I used it this week to help keep my forearms in shape for work and not letting them get used to doing NOTHING.
I think it's grip work, if it isn't sorry.
