Why "The Biggest Loser"? "It's such a dominant show in terms of health and fitness and truly helps people transform their lives. It's something I've been doing my entire life. I can now do it on a bigger scale."

His philosophy: "Over the years, I've been more than just a trainer. I've been a friend. I've been a life coach. You'll see it on the show as well where I'm able to connect with the contestants that way."

What he's learned so far: "When I hear their stories, some of them are similar to mine. I definitely learned a lot about facing my demons and dealing with issues. I can't be too specific yet because there are episodes coming up that will disclose that."
