My mom is great and I make sure that we pray together before every race. She helps me put everything in perspective and remind me of the real reason I run.

Most people don't think about plyometrics when they think about powerful strength. But I do lots of them to build mine.

I spend around two and half hours on the track every day running and another 2 hours in the weight room lifting weights with my strength coach.

I always look back to my first Olympic medal in 2004 in Athens. I was very new to the sport, and it was my first big win at the Olympics.

I used homeopathy, acupuncture, yoga and meditation in conjunction with my chemotherapy to help me get stronger again after the cancer. I also chanted with Buddhist friends and prayed with Christian friends. I covered all my bases.

I like running and swimming, and exercise four or five times a week, but not for long - about 30 minutes. I just exercise by myself and find that as I get older it becomes easier. In school I remember not enjoying running at all.

Green' issues at last are attracting serious attention, owing to critically important links between the environment and the economy, health, and our security.

I just have to be very clear. Whether or not I lose weight or stay the same, it's purely a choice of mine for health. Not because I think that plus size, curvy, voluptuous, big bodies aren't attractive - because I think they're awesome and sexy.
