Engage on the roll down and up to flex the trunk and articulate the spine.

Other Muscles at Play
Spinal stabilizers create lumbo-pelvic stability and assist with the control of the spinal articulation.
Spine extensors stack the spine up to sitting tall.
Shoulder extensors keep a downward pressure on the bar and work with the scapular depressors to create shoulder stabilization.
Scapular depressors keep the shoulders down away from the ears.
Scapular adductors (retractors) aid in keeping the shoulders from hunching or rounding forward.
Hip flexors aid the spinal flexors in rolling down and up but should not overwork.
Knee extensors keep the knees straight, especially when lying flat.
Dorsiflexors keep the feet flexed against the poles when sitting.
Objectives
Develop strong, coordinated abdominal control to support the spine as it moves through an expanded, segmental range of motion.
Enhance spinal mobility while maintaining abdominal engagement to guide articulation smoothly in both flexion and extension.
Improve flexibility and ease in the back muscles to allow freer, more efficient spinal movement.
Build balanced co‐contraction of the abdominals and back extensors to stabilize and support the body during spinal articulation.
Increase trunk stability and refine scapular control to create a steady foundation for integrated spinal movement.
Focus on breathing to synchronize the movement.
