Start in a high plank position with your hands on the mat and the balls of your feet on your sliders or towels. Engage your abs and pull your tailbone back and down. Push down in your palms to lift your chest away from the ground and broaden the space in between your shoulder blades. Keep your legs straight and close together.
Drop your head, scoop your abs up and in, and lift your hips on a slow 4-count.
Lower your hips back down on the same slow 4-count to return to a high plank.
