Melissa said a high plank targets your entire core (even your deep core like the transversus abdominis, or TVA). It also targets your back, deltoids, and legs as secondary muscles, she added.
- 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 this position for 30 seconds.
