Objectives

Develops spinal rotation while maintaining lateral flexion.
Strengthens the posterior spinal rotators to generate the force needed to press the pedal downward with control.
Strengthens and refines oblique abdominal control while lengthening the spinal rotators.
Increases mobility through the thoracic spine for smoother, more expansive rotation.
Builds pelvic and leg stability to support controlled torso movement.
Focus on breathing to synchronize the movement.
