Objectives
Increase ease and articulation through the thoracic spine.
Lengthen the shoulder extensors while softening tightness in the shoulder flexor and chest.
Encourage spaciousness across the front body as the arc’s gentle pressure supports release through the spinal extensors.
Sustain a steady abdominal connection as the spine extends over the barrel and the body reaches into a long, open line.
Focus on breathing to synchronize the movement.
