As the follower, mirror your partner’s steps as closely as possible. At the same time that they move their left foot forward, your right foot must go backward.

As your partner steps diagonally with their right foot, mirror the step backwards. This step lasts for one beat, so you must step quickly.

As your partner moves back in the second phase, you move forward. Mirror their right foot moving backward with your left foot moving forward. Imagine your foot is pulled by their foot. Go slowly so this step takes two beats to accomplish. Be sure to shift your weight onto that left foot so you are ready to take the next step. Move your feet back to parallel with this step. Make sure they are still shoulder width apart and directly across from your partner’s feet. Be sure to step quickly so it takes one beat.
