Experience the transformative promise of Pilates to produce visible results. It won't just give you a sleek, strong core -- it will also tone your thighs, and boost your buns as well as sculpt your arms and back.

The turn of a new year means resolutions. If your list for the new year includes transforming your body into a slimmer, shapelier silhouette, this workout -- based on The Pilates Promise (DK Publishing, 2004), by certified Pilates instructor and licensed physical therapist Alycea Ungaro -- produces dramatic results in just six weeks.

At the program's core are five fundamental Pilates moves that strengthen and trim your torso. "People notice their waists get smaller almost immediately," says Ungaro, owner of reaL Pilates, a studio in New York City. Then, you'll choose a goal -- streamline your bottom or strengthen and define a weak upper body -- and add three moves targeting that trouble zone.

Stick with our program, and you too could realize the promise of the discipline's founder, Joseph Pilates: In 10 sessions you'll feel the difference, in 20 sessions you'll see the difference and in 30 sessions you'll have a whole new body. Who can pass up a pledge like that?
