Wow. Now that's some serious sizing! I size mine with a hand press while sitting in front of the TV. 
Last night I was sizing some rifle bullets (16bhn) down from .284 to .278 and it took a little extra forearm exercise, and while it still wasn't quite what I'd call a workout, that thing would have made it quite fun!
