Rachel Weisz's Trainer Tips to Drop 5 Pounds

When a Hollywood celeb has to get slim and sculpted in a jiffy, she hires a slew of professionals to whip her into shape. The rest of us, unfortunately, don't have that luxury -- until now. We asked celebrity trainer Gregory Joujon-Roche, and his Los Angeles-based Holistic Fitness team of nutritionists and chefs to come up with a fast program that's guaranteed to help you drop 5 pounds, blast fat and firm up everywhere. The team's methods have worked for such clients as Demi Moore, Rachel Weisz, and singer Avril Lavigne, who have all called on Holistic Fitness to help them reach their better-body goals.

Joujon-Roche and his experts walk you through their exclusive, results-guaranteed program:

• High-intensity cardio training five days a week for a minimum of 30 minutes. They advise full-body cardio activities where you use both upper- and lower-body sculpting, such as kickboxing, flowing power yoga and rowing.
• High-intensity weight lifting with free weights or machines three days a week. Lift on non-consecutive days, so your muscles (chest, back, arms, legs, abs) can recover in between. This also means at least 15 minutes of targeted ab training three days per week.
• A lower-fat diet of 1,500 calories per day [for women], and health-promoting habits from the start. "From day one, we encourage you to maintain an exercise-diet journal, take a multi-vitamin, and drink 10 glasses of water and green tea daily," says Joujon-Roche. "Plus, start eating a high-fiber, protein-packed diet that fuels your body, sustains willpower and revs up your metabolism."

Here are Holistic Fitness' top nutrition tips:

1. Always eat a balanced breakfast, and then eat 200 to 400 calories every four hours or so to stoke your metabolism.
2. Focus on filling your plate with wholesome, natural foods while boosting your energy expenditure with stepped-up exercise.
3. Don't get stuck in a repetitive eating mode where you prepare the same salad for lunch every day, or always eat a chicken breast for dinner.
4. Stick to proper serving sizes. One serving is one piece of fruit or one cup of cooked or chopped vegetable; one slice of bread or tortilla; 1/2 cup cooked brown rice or other grain; one cup of soy, skim or rice milk; up to four ounces of fish, poultry or lean meats.
5. Eat unprocessed, whole foods as often as you can, from organic eggs and salmon to organic dairy products and poultry. "Organic products are commonly found on most grocery shelves across the country," says Joujon-Roche.
