We know that Hilary Duff [1] loves Pilates, but now we get to see the pay off of all that ab work [2]. Hilary shows off her bikini body in the upcoming issue of Shape [3]. Yep, she is the cover girl for August.

Here are a few of her health secrets:

• Exercise: Pilates [4], swimming and treading water, which helps her "firm up." She believes a workout shouldn't be boring or overly strenuous, and Pilates definitely fills those requirements.
• Diet: Lots of protein, lots of veggies and oatmeal for breakfast. Hilary believes in finding a healthy mix and making trade offs. It is OK to eat your favorite foods, like dessert, but only after skipping the pre-dinner bread basket.
• Health: When she turned 16, Hilary decided to get in shape and get healthy. She is part of the Stay fit. Eat right. Looking good, California [5] campaign, which is dedicated to bringing healthy food to school cafeterias across California.

Hilary turns 20 in September but her healthy philosophy sounds levelheaded and wise:

Stay healthy, eat healthy, eat what is good for your body and what gives you energy -- and feed your sweet tooth every once in a while. That is the best way to go.

Thanks, Hilary. I couldn't have said it better myself.
