Start in full plank position with hands and feet shoulder width apart, a neutral back and wrists aligned with shoulders. Hop your feet to either sides of your hands, then back into plank position in a fluid, controlled motion. It's ok to wait a second before hopping forward again. While performing this movement, take extra caution to keep your hips and back from dipping toward the ground.
