The Prone Plank

A super-simple, do-anywhere move that zips up your abs a la Ms. Stefani. (Fingers crossed.)

Do it:

• Get into a full pushup position with your palms on the floor beneath your shoulders.
• Hold here for 30 seconds, with your abs contracted and your arms and legs extended and your head aligned with your spine.
• As you build strength, hold this position longer, up to one minute.
• Go deeper: Try the one-arm stable switching plank.
