I was terrified to do 'G.I. Joe.' I had no idea how to do one of those movies. I was kind of scared. You know, if one of those doesn't work, it's a huge hit on your career. People are like, 'Well he couldn't make a $170 million movie work. I don't want him in my film.'
Truthfully, this is how I approach my workout: I want to be the best athlete I can possibly be. If I can out-perform some of the better athletes then I'm happy. When I look at the NFL or the NBA, these guys look how I want to look - it's useable, functional muscle.
