The Fit 5: Tips to Feel (and Look) Like a Star!
TAKE UP WEIGHTS
Ashlee Simpson Wentz admits youth and genetics helped her bounce back after the birth of 8-month-old son Bronx. “I lucked out,” she says. “I’m 24 years old and got the genes from my mother.” But the Melrose Place star isn’t just relying on good fortune to keep her fit: She’s hitting the weights in her trailer on the show’s set. “I’m just now getting back into it,” she says. “When I’m sitting around on set it gives me something to do.” Toting Bronx around has its advantages, too. “My son is really big and so he helps me out.” – Scott Huver
GET TO THE 'CORE'
Cameron Diaz and Kate Hudson are fans of the Exhale spa’s Core Fusion classes, a mixture of core conditioning, Pilates, yoga and the body-sculpting Lotte Berk Method. Now creators Fred DeVito and Elisabeth Halfpapp are helping people target their trouble zones with the Exhale: Core Fusion Thighs & Glutes DVD ($13), a series of five 10-minute workouts aiming to tone your legs, lift your booty and whittle your waist. – Serena Kappes
WORK IN CIRCLES
Karina Smirnoff, who gets “bored very easily” when it comes to working out, likes to mix up her exercise routine. One of her favorite ways to stay in shape? “Gyrotonics – it’s all based on resistance and you don’t actually use weights. You actually stretch out as you tone up,” the Dancing with the Stars pro says of the exercise done on specialized machines and utilizing circular movements. Another benefit: gyrotonics helps strengthen connective tissues around the joints of the body. “It’s one of the best things if you have an injury to recover [from] – beautiful!” – Karen J. Quan and Jenny Sundel
To get ready for her run in the Las Vegas burlesque review Peepshow, former Danity Kane diva Aubrey O’Day is working on building her energy. The singer, who posed for Playboy earlier this year, runs three to six miles every day. “It’s important to have a lot of stamina when you’re on stage eight shows a week,” she says. “There’s a lot of pressure to keep up.” And there’s another exercise the songstress says she couldn’t live without: “I like my butt to be nice and perky, so I do a lot of squats,” she adds. – Jessica Wedemeyer
After vowing to get in better shape in May, Sherri Shepherd says writing about it on Twitter made her progress even faster. “I think I would have fallen a lot more if I didn’t have people Tweeting me saying, ‘I’m doing this with you,’ ” she says. “People were holding me accountable.” Besides eating healthy with Fresh Diet food-delivery service, The View cohost hit the gym four times a week with her trainer Don Scott. And she revealed her bathing suit-ready body on the Aug. 6 episode of her talk show. Her main inspiration? Son Jeffrey, 4. “I really wanted to get healthy because I want to be there for him,” she says. – Michelle Tan
