To keep her body toned, the star swears by regular Pilates sessions. Steal five of her fave exercises from her longtime trainer Jared Kaplan, the owner of eco-chic Studio 26 in New York City. "Lucy does these on a reformer, but I've modified them for a mat," Kaplan says. "Instead of counting reps, continue until just before your form starts to falter."
Targets core, hips, butt, and legs
Stand with feet hip-width apart, hands on hips.
Lower into a squat as you step right leg directly out to side.
Step right foot back in as you stand up to return to start. MAKE IT HARDER: Using gliding discs or a towel on hard floor, slide foot out and back.
