Celebrity Workout Secrets: 17 Fitness Tips

Celebrity Fitness Tips 1-8

What smart, exercise-loving, fiber-eating woman would think she could get a better body by doing what Hollywood types do? Me -- when I know the advice comes from a sane celebrity trainer who takes wellness seriously. (I also subscribe to dancer Martha Graham's theory that "You are unique, and if that is not fulfilled, something is lost.") Here, because a Fit Girl clearly is the new It Girl, the moves to make you your very best, all vetted by our in-house FITNESS gurus.

1. Ooze Confidence
Tyra, we love you because you strut with confidence. Banks's "SO WHAT!" campaign, which encourages women to embrace their bodies -- flaws and all -- shows that even supermodels can champion the beauty of being super-real.

2. Hit the Road Penelope Cruz gets her fitness outside. "Workouts aren't just about burning calories, they're about getting in shape for the things you love," says trainer Gunnar Peterson. For more ways to get fit without having to step foot in a gym, see our outdoor workouts feature.

3. Be a Fit Mom
To shape up for her upcoming movie, The Kingdom, Jennifer Garner did lots and lots of lunges with shoulder presses, says trainer Valerie Waters. In real life, toddler Violet stands in for some dumbbells.

4. Get on the Ball
Jessica Simpson uses one for wall squats, says trainer Harley Pasternak, keeping the ball behind her back to maintain proper form as she sculpts her legs and butt. For more stability ball moves, check out our insider's guide.

5. Build Strong Bones and Muscles
Trainer Joe Dowdell has actress Claire Danes hoist some hefty weights during her high-intensity workouts.

6. Swing into Action
Catherine Zeta-Jones hits the links for some R&R. If she forgoes the cart and carries her own clubs, she'll burn about 261 calories an hour.

7. Two-Step
Boxer Laila Ali says doing some fancy footwork on Dancing with the Stars required the same focus and intensity she finds in the ring. We say she looks amazing.

8. Focus on Yourself
"It's important to get out of your head and into your body," says trainer Gregory Joujon-Roche, who works with Avril Lavigne. "Do whatever feels good, because that's what it's really all about."
