Objectives
Enhance deep abdominal control to stabilize the body while allowing smooth arm and shoulder mobility.
Bringing the arms in toward the chest with bent elbows before rolling down helps the body stabilize during the shoulder rotation and the straightening of the arms.
The emphasis is on maintaining abdominal stabilization during the movement.
Shoulder lubrication as the spine moves through flexion and extension.
Control and precision of arm movements and spinal movements to loosen both shoulder girdle and the spine.
Differentiates the shoulder from the spine & teaches scapulohumeral rhythm.
Focus on breathing to synchronize the movement.
