I've always believed that the facts about dancing are more interesting than the myths, and this was a great chance for me to explore how the human body does such incredible things.

I always recommend a sensible diet, including lots of carbohydrates and avoiding too much fat. Dancers don't need different fuel from other people - they just need more of it because they use more energy.

You can't reduce lactic acid, but you can increase your tolerance to it. I do this through running or cycling, but it's a good idea to match your training bout to the type of dance you do.

But you do have to start young as a dancer if you're going to achieve the physical skills necessary.

It's not about weight, it's about fitness, and one component of being fit is to have relatively low body fat, because fat is not very efficient, whereas muscle is.

I enjoy the freedom of modern dance as well as the constraints of classical dance.

Dancing is a tough career, but I'm glad I spent it at the Royal Ballet.
