Secrets of a Hollywood Body

J.Lo is in her best shape ever thanks to a regimen of cleanses and customized workouts with Tracy Anderson. "She loves a five- or 10-day Optimal Cleanse from East West Essentials," Jennifer's nutritionist, Haylie Pomroy, tells Life & Style. "It's a combo of food and shakes that enhances metabolism and detoxifies the body," Adds Anderson, "We do leg and butt-lift exercises that change every 10 days, so nothing gets neglected."
