Start with many chair stunts all lined up in a row. This can be down with COED (as shown in the pic) OR with all-girl teams (you can include a spot if needed).

Once up in a chair, have all of the flier connect arms and pull their stretches with their right leg. The far right flier will hold her own and the other stretches can either be placed up on the connected arms OR held by the flier herself for the finish.
