Objectives
Develop control of spinal articulation through a clear, segmental movement pattern.
Develop abdominal, hip-flexor, and hip-extensor control while articulating the spine to support coordinated, balanced motion.
Increase strength in the abdominals, back extensors, and hip extensors & knee flexors to maintain control of the bar throughout the movement.
Increase deep abdominal control to facilitate effective co-contraction of the abdominals and hamstrings.
Maintain consistent scapular stabilization while articulating the spine to support clean upper-body mechanics.
Focus on scapula stability as an anchor point.
Focus on breathing to synchronize the movement.
