"What Olympians eat can vary tremendously depending not only on the events they're competing in, but also their body type and lifestyle outside the Olympic arena. Their diets are affected not only by the demands of their sports, but by everything else in their lives, things that are almost impossible to accurately measure and factor in."

"Most days, I have a slice of toast, then lie in a hot bath for an hour to get up a sweat. I have a sauna at the racecourse and then go and ride. On the way home, I might stop at a service station and have a bar of chocolate and a Diet Coke. And that's it, basically."

"Much in the way Olympic athletes optimize their game by paying an enormous - borderline maniacal - amount of attention to things like diet, exercise, sleep, and of course the essential R&R, we all would do well to pay more attention to those key aspects of our lives that comprise our overall health equation."

"Energy drinks like Red Bull may give you wings for the moment, but in time it takes away your basic physical and mental wellness and leads to disastrous psychiatric and physiological conditions."

"I don't want to be knocked out. But the contact and the focus and the energy I get from sparring gives me energy to make movies, energy to be a dad, energy to be a friend, and, you know, makes me feel, probably, a lot younger and behave a lot younger than I am."

"Unfortunately, diet is 75 or 80 percent of trying to get in shape, so you do have to try to cut the carbs. The diet's a huge part! I'm from Kansas, so I love ranch dressing and McDonald's. When I'm working, I have to stay away from all that!"

"I'm sure I frustrate the trainers - in fact, I know I frustrate the trainers to no end. But I think there's a very fine line. I listen to their advice. I take their medical expertise very seriously. But then I also, the reason I am where I am, the reason I play the way I play, is because I push beyond normal."
