Objectives
Mobilizes the spine through full flexion and extension, promoting segmental movement.
Strengthens the abdominal muscles, with lower spring settings increasing the demand on core control.
Strengthens the back extensors, with heavier spring loads providing greater resistance and muscular engagement.
Both strengthens and stretches to support scapular stability, while also engaging the anterior cervical muscles.
Strengthens the posterior deltoid, elbow flexors, serratus anterior, upper trapezius, and obliques during rowing movements.
Strengthens the middle and upper trapezius, along with the back extensors, when the spine moves into extension.
Focus on breathing to synchronize the movement.
