Jessica Biel: I sometimes work out five hours a day

Jessica Biel is obsessive about working out, and the results are evident in her incredible bikini photos.

"I've worked out five hours, sometimes more, in a single day if I'm in training for a film role," Jessica, 27, recently admitted. "And it's hard, very hard!"

Biel, who is dating singer Justin Timberlake, 28, says the pressure to look good for movie roles is what motivates her to hit the gym.

Cardio + Weights

Jessica varies her workouts to work all her muscle groups as well as to avoid monotony. For cardio, Biel usually jogs for ½-mile and then does intervals of 100-meter, 200-meter and 400-meter sprints.

Jessica also does weight training (with light weights and high repetitions) to keep her muscles taut and lean and rests minimally in between sets to maximize her aerobic fat-burning.

Focus on Portion Control

As for diet, Biel tries to limit processed foods and exercise portion control. For breakfast, Jessica usually likes complex carbs, such as oatmeal with berries, and then snacks on fruit or whole wheat toast dabbed with almond butter. For lunch and dinner, Biel usually has a chicken or fish entree with vegetables.

"Eat things you like, but in smaller portions," says Jessica. "I always cut things in half and send half back. Do I eat dessert? If there's something I want to try, then I try it. But I have a bite, not the whole thing."

It Ain't Easy Being Hot

Ironically, Biel recently revealed that her good looks have hurt her career. "[Being beautiful] really is a problem," Jessica told Allure. Biel, who says she covets the careers of Scarlett Johansson and Natalie Portman, even claims she has been turned away from auditions because she's too pretty. "If you don't like the audition, then don't hire me," she says. "But if you don't even want to see me, that's hurtful." (Hmmm...how does that explain the careers of Angelina Jolie, Catherine Zeta Jones,

Biel's latest film, Powder Blue (in which she plays a stripper and is featured in several nude scenes), went straight to DVD. Jessica's next film, the animated alien adventure Planet 51, hits theaters in November.
