Cara Castronuova

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.

I'm the type of person who can get a feel for what you need and what I need to do to push you to get you to a breaking point, where you realize that you can't go on this way anymore, that the reason you're heavy is because you're ignoring all the stuff that's going on inside.

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 like to eat chocolate and pizza - that's my vice! - just like everyone else, but if I do it I have to keep it under control.

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

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 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 don't care who you are or what you have gone through - everyone has something they are fighting for.
