49-year-old actress Courteney Cox Arquette stays toned the old fashioned way. "I work pretty hard at it. I eat well and I exercise all the time," Cox Arquette has said. "I'm an avid 'worker-outer.' I also like to swim and play tennis." While running used to be her exercise staple, the actress now mixes things up with resistance bands, leg weights and dance aerobics. INSIDER TIP: "My clients prefer Power Pilates machines to tone, tighten and get red-carpet ready in less time," says celebrity trainer Michelle Lovitt, who has worked with Cox Arquette. "They get a full, targeted workout in as little as three 30-minute sessions a week." TRY IT: Find a power plate machine near you or buy one now at powerplate.com.
