Start in a staggered stance, with an exercise band under the front foot. Hold the other end in the opposite side hand. Bend slightly forwards from your hips (at this point the band should be tight).
Keeping your trunk in the same position, take a long step to the side and squat down. At the same time bring your elbow backwards and pull the band. Your free arm should come forward at this time. Take a step back and return to the starting position.
