Start in a horse back riding stance with the arms extended in front of you and the palms facing outward.  As you shift to the left and turn to the left, your right arm circles down and the left circles up.
As you complete the turn and weight shift, your hands meet with the right palm facing up and the left facing down.
Pull with your right foot to start shifting and turning to the right.  The left arm goes downward as the right goes upward.  As you complete the weight shift and turn the hands come next to each other with the left facing up and the right facing down.
