Contract abs to keep your body in a straight line and spine parallel to the floor. Abs should be pulling toward the ceiling. The key is to hold it for as long as you can.” Lagree recommends starting out by holding for 20 seconds and working your way up to a minute, or longer. Come down to starting position, rest and repeat three times. Want to kick it up a notch? Here’s a look at some plank upgrades.

Legs should be out straight and feet slightly scissored one in front of another. Pull your belly button in towards your spine. Raise your body up by straightening and lengthening the waist so that you are balanced on your left forearm and the bottom of your left foot; once balanced, lift arm up.” Lagree recommends holding for 20 seconds and working your way up to a minute. Rest in between, and repeat three times on each side. Here’s how to get a flat belly without a lick of exercise.
