I'm constantly feeding my metabolism. But at the same time if I want to go one night and have a nice dinner then I won't sweat it the next day.

It's not just the physical aspect of boxing, it's the whole fighter mentality that has been ingrained in me through the years as a competitive athlete. One of the hardest things you'll ever do is to box - to get into the ring and to face off with somebody whose whole goal is to knock you out, to hurt you, and to be able to fight back.

I'm constantly feeding my metabolism. But at the same time if I want to go one night and have a nice dinner then I won't sweat it the next day.

Even though I had been boxing, I had no idea I could beat somebody in the ring. And I had no idea I could really take a punch. When I realized that, I really started taking off.

My background is that of a competitive athlete and a fighter, and I'm bringing something totally different to 'The Biggest Loser' that wasn't there before.

I know that when I get stressed, I want to eat junk food. So now I just know - 'I'm stressed, I want to eat junk food, so I'm going to go work out instead, or eat something healthy.' It really works.

I'm not a celebrity trainer. I don't have my own line of DVDs, but I'm a fighter and have everything to prove.
