Jessica Alba eats healthy and works out for "Into the Blue" movie shoot.

Eat several times a day

Jessica Alba ate four to five small meals a day, every three hours, usually starting with a shake or oatmeal and fruit. Dinner was salad with chicken or fish.

Use food as fuel

Jessica Alba needed to swim and dive for many shots in the "into the blue" movie so keeping her energy level up was essential.

"My trainer (Ramona Braganza) has been with me since I was 17, so she's there whenever I do a movie. She's a good friend of mine. She gives me vitamins and makes me eat right. For this one, because the movie was so physical, I did more stretching exercises and yoga."

Jessica Alba's Workout

Trainer Ramona Braganza tells how she helped sculpt Jessica Alba's bod.

Butt:

Since Jessica Alba has sensitive hip joints, Braganza avoided jumping exercises and opted for either Pilates, walking lunges, light squats or 20 to 30 minutes on an elliptical machine every day. "She's got a beautiful bottom," says Braganza.

Arms:

Alba toned her biceps with various dumbbell curls using 8- to 10-lb. weights; three sets of at least 20 reps. For triceps, she did dips or weighted presses. She worked arms at least twice a week.

Shoulders and Back:

Alba worked on these at least twice a week, doing military presses with 10-lb. dumbbells; three sets of 15 reps. She also used light dumbbells for lateral raises. "Her shoulders get a nice square shape," says Braganza.

Chest:

Alba alternated dumbbell presses (15 to 20 lbs., three sets of 15 reps) with dumbbell flys (12 to 15 lbs., three sets of 12 reps), done on an incline bench or stability ball.

Abs:

For her taut stomach, Alba combined crunches and mat Pilates work daily. "It's gentler but strengthening," says Braganza.

Add the following to your own routine:

• Warm-up for 10-15 minutes to bring your heart rate up on the treadmill or elliptical
• 45 minutes (to one hour) of cardio
• 50 lunges to tone glutes and hams
• 50 crunches to tone abs and torso
• 10 minute cool down on the treadmill or elliptical to bring your heart rate back down
• Hydrate well with water (not too cool) on hand
