The long axis is an imaginary line running through the center of the body from head to toe. The purpose of the skill is to practice landing exactly how you started; arms over your head, feet together, and your body tightened and straight. Practicing the standing twist helps you gain awareness in the air.
The long axis represents a central line running through the body from head to toe, used for balance and orientation. The purpose of this exercise is to refine landing technique, replicating the starting position: arms overhead, feet together, and body tense. By practicing the standing twist, you develop greater awareness during flight.
