I know what you're thinking ... how do you train UFC?
The same way you become a UFC fighter without actually fighting, also known to Bruce Lee fans (Enter the Dragon) as the art of fighting, without fighting. I know CM Punk -- real name Phil Brooks -- is a UFC fighter, because this inside look at his workouts tells me so (skip to 2:33).
And he's looking HUGE and RIPPED!
The former professional wrestler is scheduled to make his Octagon debut in 2016, but that hasn't stopped him from ruffling a few feathers along the way.
