The Secret to Flat Abs (Hint: Not Sit-Ups)

Curls and sit-ups can definitely help tone your abs, but a new study suggests something else might work better.

Seems counterintuitive, but working your upper body may be the quickest path to a really sculpted middle.

Above-the-Belt Action

Shoulder extensions made middle-body muscles contract most -- apparently they work extra hard to stabilize your trunk when your wings are flapping. (Watch this strength-training video to learn how building 5 extra pounds of muscle could burn 26 pounds of fat in a year.)
