Other Muscles at Play
Objectives
Stabilizes the trunk through spinal articulation while maintaining steady support from the scapulae and arms.
Mobilizes the spine through sequential articulation and the femurs within the pelvis through controlled movement.
Teaches precise sequencing of the spine—tail to mid‐back during the rollover and mid‐back to tail during the roll down.
Challenges the endurance of the stabilizing muscles in the scapulae, shoulders, and arms throughout the movement.
Refines coordination by integrating leg movement with the articulated motion of the spine.
Focus on breathing to synchronize the movement.
