Boxing is all about how cool and controlled and clear your mind is. Violence only gets in the way of you winning a fight. It's a sport that's more about the strategy than anything. You lose or you win in your head.

Boxing, in the most general terms, is a poor man's sport. All you have is your hands to make a living.

To portray not only a boxer but a boxer like Roberto Duran, I needed to understand all the difficulties and the pressures of the sport itself.

Panamanian boxing is unique - it's very musical. It's almost like a dance. It has a lot to do with being in the Caribbean and with salsa. When you see a Panamanian boxer, there's a style. There's a playfulness in the way you throw the punches.

If you get conquered by ego, then you are losing the fight.

I thought I knew how to work out before I immersed myself into boxing. I now know what an extreme workout really is.
