Rotate the spine as the arm opens and reaches.

Spinal Flexors

Rectus Abdominis, Internal Oblique, External Oblique

Engage to roll back into the c-curve.
Maintain the c-curve throughout the rotation phase.

Other Muscles at Play

Spinal stabilizers create lumbo-pelvic stability and assist with the control of the spinal articulation and c-curve.
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 the c-curve 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 abdominal control and strength to support the spine as it rotates.
Increase spinal mobility while maintaining abdominal engagement during both the roll down and rotational patterns.
Improve both flexibility and strength in the oblique muscles to enhance rotational control.
Build coordinated co‐contraction of the abdominals and back extensors to stabilize the body throughout rotational movement.
Increase scapular stability and maintain level hips to ensure clean, controlled mechanics during the exercise.
Focus on breathing to synchronize the movement.
