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