Yoga is my luxury workout. If I'm on vacation or I have a day off, I love a 90-minute yoga class. It's a really strong workout, but it takes a little bit longer.

When I saw contestants fighting for their lives on 'The Biggest Loser,' I realized I just wanted to be healthy - to have fun playing soccer with my son or teaching my daughter to shoot hoops. Then it was so much easier to say no to carbs, soda, or dessert, and the weight just came off.

I battled with my weight as a teenager, partly because there wasn't the information or conversation about how to live a healthy lifestyle.

I keep track of my body by how my jeans fit—and how I feel.

Fitness is not an option. It's part of my job.

There are times, like after a long day of work, when the thought of an easy drive-through is enticing. But then I remember how crappy I felt when I ate fast food in the past, and it inspires me to head to the grocery store or my local farmer's market and whip up an easy but healthier option.

With reality TV, sometimes it's amazing chemistry and you get these gems that turn out to be everything you hoped, and the camera loves them and they just blossom on the show. And then sometimes it's not all you envision.
