Steal Jessica Biel's Workout Secrets

Biel's favorite exercises are the ones that "keep her butt healthy," says her trainer, movement specialist Jason Walsh. For a bum like Biel's, lunges are a must. She does a mix of walking lunges and multidirectional lunges, in which she'll lunge in a circle, doing one at 12 o'clock, one at 3, one at 6 and one at 9, says Walsh. For beginners, he recommends walking lunges: two to four sets, 15 to 20 lunges per leg.
