I work barefooted on balance plates. I do explosive squats on balance surfaces that your body has to use muscles it's not used to. It's all kinds of exercises that your body isn't really used to, and it tricks your body into getting stronger every time.

I don't look at football as a violent, barbaric sport. It's a very spiritual sport, especially for someone facing the challenges during a game: the fear of failure, the fear of getting too big an ego, of making a mistake and everybody criticizing you.

The Coca-Cola Mean Joe Greene ad is one of the most famous commercials of all time, so I was blown away when they asked me to be in this new spot.

It's the perfect environment for prayer. Chanting in Greek is like a beautiful opera, but way better.

I've never really been aware of what is said about me, whether it's positive or negative. I ignore it. I've always had the mind-set: 'No one can challenge me better than myself.'

A big hit is all part of the game. If you want to make a lot of big hits, you forget about the one you just made and move onto the next one.

The greatest thing for me football-wise is that it's a test of will.
