WORK YOUR MUSCLES

Jennie Garth toned up for her comeback role on the new 90210 by working out five days a week with husband actor Peter Facinelli to trainer Tony Horton's P90X DVDs. "Every day is different," she says. "One day is really hard yoga. Then arms and shoulders, legs, then karate. His program is made to confuse the muscles so you don't plateau. I feel better now than I ever have."
