With China and North Korea, you never know who you'll fight. The faces are always changing, and suddenly young opponents come up. It's all about winning at the Olympics, not about winning pretty. I'll just keep trying to improve, add more muscle power, and make sure I'm the last one standing.

Fear is there. Anything can happen at an Olympics. I want to use the experience I gained from Athens and Beijing - the fear, too - and build a me that can't lose. I will do everything to make sure I win a third gold medal in London. That target drives me. I'm bulking up and have more power now. I'll be fighting fit to take the gold back home.

London was the hardest Olympic Games, and before it, I was really just hoping to win a medal, even if it was not the gold medal. At the same time, I have my next target. I am not settling for three golds in a row. I now want to try for a fourth.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
