If you want a dancer's body, dance. Dance aerobics is my favourite cardio. It's very frustrating if people think you have to become a dancer to do it - you don't.

All my clients eat. Madonna has a very healthy appetite. She doesn't eat processed food, she's very conscious of the quality of the things she eats but she has treats - she loves cupcakes.

Oftentimes, heavy weights can tear the muscle fiber causing it to bulk, but using a lighter weight for a longer duration and allowing your body to move in many different ways to target all of the muscles will lengthen them without tearing.

Madonna is an athlete; she has to be treated like a professional athlete. She doesn't work out for six hours a day, though, like some of the press says. She never works out for more than two hours a day, and then only when she has the time.

I hate diets and I love eating.

I have done research about people who think they're doing movements and people - like Madonna and professional dancers - who are actually 'performing' movements. The people who can connect and perform during their workout get results way above and beyond the people who are just going through the motions.

I tell people to be thankful that Madonna is showing that it's possible to be ageless - people should applaud and celebrate that. Anybody who criticises her is just jealous!
