Ab Circuit, Exercise 4: Plank Hip Dip
- Begin in a forearm plank. Make sure to keep your shoulders away from your ears and your back flat.
- Pull your belly button in toward your spine to keep your abs engaged as you drop your hips to the right side of the mat. With control, engage your core and return back to the center, then drop your hips to the left side, and return back to the starting position.
- This counts as one rep. Alternate for one minute.
