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. ”

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. ”

Everyone has a different training style and being a female, sometimes you find you have to get really aggressive. Some people respond really well to aggression, some people don't. ”

Nothing would make me happier than to train the next winner on 'The Biggest Loser' because it means the world to me. Everybody has a fighter inside them, they just don't realize it. ”

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. ”

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. ”

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. ”
