Muscle Focus
Hip Adductors
Adductor Longus, Adductor Brevis, Adductor Magnus, Gracilis, Pectineus
Crosses the gesture leg over the midline.
Resists the spring so the gesture leg opens at a controlled distance as it circles.
Closes the gesture leg to the midline.
Build midline connection to the core.

Hip Extensors
Gluteus Maximus, Hamstrings: Semimembranosus, Semitendinosus & Biceps Femoris
Presses the gesture leg down to the mat or circles down.
Resists the spring as the gesture leg circles up or lifts up.
Keeps the stable leg pasted to the mat.

Hip External Rotators
Gluteus Maximus, Piriformis, Obturator Internus, Gemellus Inferior, Gemellus Superior, Quadratus Femoris
Maintain the turn out of the thigh in the hip throughout the exercise.
Assist the hip extensors to press the gesture leg down and resist up in the circle.

Spinal Stabilizers
Transversus Abdominis, Erector Spinae, Semispinalis, Deep Posterior Spinal Group
Create lumbo-pelvic stabilization.
Keep the trunk stable against the unilateral movement of the leg.
Maintain ribcage placement so the ribs don't pop and the back doesn't arch.


Other Muscles at Play
Spinal flexors work with the spinal stabilizers to control ribcage placement and stability of the trunk and pelvis.
Scapular upward rotators allow for overhead reach to push into the bar to keep the shoulders down and wrapped under the armpits.
Scapular depressors keep the shoulders down away from the ears.
Elbow extensors keep the arms straight.
Knee extensors keep the legs straight.
Objectives
Develops strong control of the hip adductors, external rotators and extensors while keeping the pelvis deeply stabilized.
Enhances abdominal strength to support smooth, organized movement of a single leg.
Improves precision and power in the adductors on the moving side while the opposite side stabilizes.
Maintains steady, centered pelvic and spinal stabilization and alignment, preventing any side-to-side rocking.
Focus on breathing to synchronize the movement.
