Exercise posture: Feet shoulder width apart, soft knees, abs/glutes engaged, shoulders back and head neutral.
Begin by shifting weight into one leg and peeling the other leg off the floor. Once you lift the leg up, take a big step forward as if you are stepping over something. Make sure the momentum is going down and not continuing to go forward and placing stress on the front knee. Once the front leg is parallel to the ground, push off that leg to return to exercise posture and repeat movement.
