She has one of the hottest bodies in Hollywood, but Jessica Biel would be the first to say it’s not all in the genes. Life & Style met up with the 27-year-old on June 26 as she endured an hour of boot-camp-style moves at Live-in Fitness Enterprise Inc. in Marina Del Rey, Calif. And the intensity of the workout was evident. “I’m not just glistening — that’s all sweat,” she told Life & Style after completing the routine. “It was tough, and I’ll definitely be back for more. But I’m tired!”

The program (found at liveinfitnessenterprise.com) provides customized five-to-seven-hour exercise plans, which Jess’ Iron Ocean Films partner and workout buddy Michelle Purple suggested the star try. Of course, Jessica is used to pushing herself to the limit. “I’ve worked out five hours, sometimes more, in a single day if I’m training for a movie role or something,” she says. “And it’s hard. It’s very hard!”

While diet and exercise don’t consume her, Jessica incorporates them into her daily routine. “Health and fitness are a part of my everyday life,” says Jessica. “I’m not perfect, of course. But I do make them a priority.”
