BODY WATCH : TRY THIS ON A PLANE, AT YOUR OFFICE OR HOME

Chin Tuck: Sitting straight in your chair or seat, gently pull your chin straight back toward you--without tilting your head--making a double chin. Relax and repeat.

Tummy Tightener: With feet together, sit on the edge of your chair and place a phone book on your lap, holding it with one hand. Keeping your back straight and your knees bent, raise and lower your legs about four inches, until your feet are off the floor and you feel your lower abdominal muscles contract.

Calf Stretch: Stand, place your hands on your desk and lean toward the desk. Stretch one leg behind you and straighten it, keeping your heel on the floor. Hold for a few seconds. Repeat with the other leg.

Thigh Stretch: While sitting, gently bring your thigh to your chest and hug your knee. Repeat with other leg.

Biceps Bulger: Holding a book, a stapler, anything heavier than a paper clip in front of you, and keeping the elbows close to the body, slowly curl your arms toward you. This can be done with both arms or you can alternate arms.

IN YOUR (STOPPED) CAR

Face and Neck Toners: These require the driver to contract his or her face and neck muscles by making grimaces and funny faces. The possibilities are endless. Puff your cheeks full of air and hold your breath; open your mouth wide in a silent scream; smile or frown broadly. Be creative. Expect stares.

Steering Wheel Curls: While stopped, grasp the bottom of the steering wheel, palms up, and pull toward your chest. Hold for 10 seconds and relax. Repeat three to five times.

Military Ceiling Press: Place one palm on ceiling of car and press upward. Hold for 10 seconds and relax, repeating three to five times with each arm.

Chin Dips: This requires the driver to place one hand on the forehead, while attempting to push the chin down toward the chest. The counter-pressure of the hand is meant to keep the head in place.
