Celeb Trainer Tips: Get Your Sexiest Body

Get Sexy Abs

Try Cardio
"You need to burn fat with cardio (at least 30 minutes, three to five times per week) to see ab definition, says Teddy Bass, who's trained Lucy Liu and Cameron Diaz. "Elliptical machines are great, because you have to contract your abs in order to stay upright." Or try Pilates, cycling, or kayaking.

...and Sculpting
Targets: Obliques and transverse (deep) abdominal muscles
Lie faceup on floor, with right foot on left knee and hands behind head. Engage abs and lift hips and shoulders off floor while bringing left elbow toward right knee. Lower. Perform 20 reps. Switch legs and repeat; do 3 sets per side.

Fake It
"To show off a flat tummy, wear thin, knit fabrics (clingy -- not too tight). Or layer a cropped jacket over a long, lean tunic," La Morte says. "Want to hide your abs? Wear tops with wide Empire waists."
