Jennifer Aniston's arms, Cindy Crawford's abs, Michelle Pfeiffer's legs and Claudia Schiffer's rear end. Sound like a recipe for the unattainable dream woman?

According to a new book by trainer-to-the-stars Kathy Kaehler (search), your very own "Hollywood" body is just a hop, skip and a "pylo push-up" away.

In her book, out Tuesday, Kaehler, reveals the exercises that have helped her famous clients get in shape.

Since landing a job at a Santa Barbara spa opened by Jane Fonda in 1987, Kaehler has worked with dozens of stars including Schiffer, Barrymore, Aniston, Crawford, Julia Roberts, Melanie Griffith, Candice Bergen and Lisa Kudrow.

Kaehler insists stars are not all blessed with perfect genes and that they face the same obstacles we all do to achieve those red carpet bodies.

"Celebrities are not all that different" from everyday people," Kaehler said. "They are all busy people, they have families to take care of and things to do. They work hard to look as great as they do.

"They do have the additional motivation of appearing in front of cameras every day, so they have to look their best, but still they have to stay dedicated and focused, just like anyone else."

Kaehler continues to work with a number of Hollywood stars, hosts a regular fitness segment on NBC's "Today" show and is a spokeswoman for several fitness groups.

The Los Angeles-based mom of three says she wrote the book to share her knowledge with everyone, whether or not they are likely to walk down a red carpet or star in a Hollywood blockbuster anytime soon.

Following is a selection of exercises from "How to Get a Hollywood Body in Just 30 Minutes a Day.'' (search) The Tinseltown career is up to you.

Drew Barrymore

Target: Arms

Drew Barrymore realized a role in "Charlie's Angels" would mean challenging stunts in skimpy outfits -- so she called Kathy Kaehler for help. Barrymore confided that the size of her bust had stopped her from finding a comfortable workout, so Kaehler recommended a sports bra from Enwell (www.enwell.com) that Drew said "changed her life." The two worked out four times a week for eight weeks before filming.

Exercise: Pylo push-up with a clap

Lie face down on the floor with your knees bent, your feet lifted above your knees, and your hands on the floor slightly wider than shoulder-width apart. Keep your head, neck and back in a straight line, with your belly button pulled in. Push up, using momentum to propel yourself up off the floor, and clap your hands in the air. Land on your hands and lower yourself down for the next pylo push-up. Start with two sets of five and work up to two sets of 10.

Cindy Crawford

Target: Abs

Like any new mom, supermodel Cindy Crawford was worried about getting back into shape after giving birth to her first child. So she called Kaehler and suggested the two of them create an exercise video to help new mothers work out.

Exercise: Card sit-up

Hold 15 playing cards in your left hand. Lie on your back with your knees bent, feet on the floor, arms extended above your head. Exhale as you use your ab muscles to lift your torso up into a seated position, simultaneously using your right hand to deal a card onto the floor in between your legs. Lower to starting position, then repeat until all cards are dealt. Next continue the sit-ups, picking up one card at a time until all cards are back in your left hand.

Michelle Pfeiffer

Target: Legs

The thought of appearing on camera in a black vinyl bodysuit would make most women weep. So when she landed the role of Catwoman in "Batman Returns," Michelle Pfeiffer called Kathy Kaehler. The actress had to be on set by 6 a.m., so the pair had to drag themselves out of bed for 4:30 a.m. workouts each day.

Exercise: Side-to-side hop step

Take a long piece of masking tape and tape it to the floor in a vertical line. Stand to the left side of the tape with your feet together, arms by your sides. Hop with your right foot, then your left foot, over the tape, exhaling each time you push off your feet, landing with your knees slightly bent. Repeat the move, hopping to the left. Continue alternating sides until you've done a total of 20 hops in each direction.

Claudia Schiffer

Target: Butt

Kaehler describes her first meeting with Claudia Schiffer as a scene out of "Candid Camera."

After arriving at the home of Schiffer's then-boyfriend, magician David Copperfield, Kaehler rang the doorbell by pressing the breast of a lingerie-clad mannequin.

Kaehler and Schiffer went on to record an exercise video called "Perfectly Fit."

Exercise: The hip lift

Lie on your back in front of a chair, with your knees bent and your heels on the chair seat. Your knees should be directly above your hips, your arms by your sides. Exhale as you press your heels down into the chair seat and squeeze your buttocks until your hips lift off the floor. Pause then lower your hips back down. Do this 10 times. Rest for 30 to 60 seconds, then repeat.

Jennifer Aniston

Target: Shoulders

Kaehler began working with Jennifer Aniston in 1994, when the popularity of "Friends" was beginning to grow.

Little did Kaehler know that the unassuming 25-year-old actress would end up marrying the sexiest man on earth and revolutionizing women's hairstyles.

But Kaehler can take a little credit for are those perfectly shaped and toned shoulders and upper arms.

Exercise: Shoulder shrug

Holding weights (3 pounds or more, depending on strength), stand with your feet shoulder-width apart, chest lifted, belly button pulled in, arms by your sides. Pull your shoulders back and down as far as they go naturally. Keeping your back straight, exhale as you slowly shrug your shoulders to your ears. Inhale as you slowly lower to starting position. Keep the movement very controlled. Do this eight times.
