Four-Minute Ab Workout
This Ab-Strengthening Plank Workout Is 100% Hard but 100% Good — Here's How to Do It
- Start resting on all fours.
- With your palms flat, raise up off your knees onto your toes. Keep your hands directly below your shoulders.
- Contract your abs to keep yourself up and prevent your bottom from sticking up. Remember to keep your belly button pulled in.
- With your head and spine in line, keep your back flat — don't let it curve. Picture your body as a long, straight board.
- Hold for 30 seconds.
