Want A Bod Like Hilary Duff?

Pilates does a body good..just ask Hilary Duff. "I was a gymnast before, so I was a bit more bulky in the past. [Now] I have leaner longer muscles, my strength is up," she tells PEOPLE. Duff does Pilates three times weekly "for flexibility and toning," she gets her cardio boost from doing Piloxing – a combo of Pilates and boxing.
