Particular attention is paid to the dimensional stability of the flyer. Small changes by shortening the abdominal, lateral or back muscles significantly change the center of gravity and the flyer starts to tilt. In order to get from standing to the respective lying position, the flyer will lean in that direction and then be picked up. Although leaning in the opposite direction is instinctively made, unfortunately only increases the effort of the base. Often, tilting by the base is thereby also prevented, e.g. from the belly flier to the shoulder stand.
Once the flyer has arrived in the desired position, he may still operate aesthetic cosmetics.
