“We talk a lot on 'Biggest Loser' about how fitness is a natural antidepressant, how it burns off stress. What I like about running is that it gives me time alone. I'm always busy, with people at work, with my kids. I love getting out for a run by myself and just listening to my music.”

“I don't smoke, don't drink much, and go to the gym five times a week. I live a healthy lifestyle and feel great. I can run a marathon, you know.”

“My weight fluctuates depending on my mood and my current devotion to my fitness routine.”

“I think if you exercise, your state of mind - my state of mind - is usually more at ease, ready for more mental challenges. Once I get the physical stuff out of the way it always seems like I have more calmness and better self-esteem.”

“I'm 33 now and I seem to have hit a fitness plane. Shifting the wobbly bits isn't as easy as it used to be.”

“Never hurry. Take plenty of exercise. Always be cheerful. Take all the sleep you need. You may expect to be well.”

“Take care of your body. It's the only place you have to live.”

“I can't eat whatever I want, definitely not. I'm always controlled because I do a lot of fitness and triathlons, not just Formula One, so I always make sure I eat the right things.”

“I feel if I'm healthy and happy, I look good. With a good mixture of fitness and healthy food I always feel great!”
