Oh yes I remember CT mentioning those. Will have to figure out at which level to start though, the No.1 seems a bit over the top, maybe Trainer.
Heavy bar holds and hanging from a pull-up bar are great for building endurance. You could get some “Captains of Crush” grippers from IronMind.com. I also have a dumbell that has a 5lb plate on only one side that I use for wrist rotations and “Hatchet Chops”.
In addition, I find that doing as much deadlifting and shrugs as possible before you resort to wrist straps will really build your forearms and grip strength. Like most people though, the bar will slip out of my hands well before I’ve worked the target muscles well enough so I do use straps on my last sets.[/quote]
