Objectives
Strengthen the oblique abdominals, back extensors, and lateral trunk flexors to build a powerful well‐integrated support system for side‐bending work.
Develop precise control of lateral flexion by moving the spine while keeping the pelvis stable, reinforcing clean mechanics and balanced muscular engagement.
Creates a broad, lengthening stretch through the lateral flexors, allowing the entire side body to open and decompress.
Focus on breathing to synchronize the movement.
