Objectives
Teach external rotation from the center of the body— initiating from the deep rotators and powerhouse rather than simply turning the legs out—so the movement is organized, supported, and integrated.
Create length through the spine by encouraging axial elongation, allowing the trunk to stay lifted, spacious, and aligned as the legs work.
Develop the strength, mobility, and coordination needed for exercises like Crab on the Mat by training controlled spinal flexion, deep abdominal support, and fluid hip movement.
Use the abdominals to maintain a clear connection of the low back to the barrel as the legs move away from the body, reinforcing deep core support.
Focus on breathing to synchronize the movement.
