Right arm positive circle while the waist turns left to set up. When executing, the waist turns right and then to the right again (two beats) while the right arm is doing one beat with elbow moving to the right in a negative (bottom portion) circle. In this video, the elbow was not physically used but the actions are exactly the same.
