Muscle Focus
Hip Adductors
Adductor Longus, Adductor Brevis, Adductor Magnus, Gracilis, Pectineus
Beat the legs together.
Resist the springs so the legs open at a controlled distance.
Build midline connection to the core.
Hip Extensors
Gluteus Maximus, Hamstrings: Semimembranosus, Semitendinosus & Biceps Femoris
Push against the springs to keep the legs straight down toward the mat.
Spinal Stabilizers
Transversus Abdominis, Erector Spinae, Semispinalis, Deep Posterior Spinal Group
Create lumbo-pelvic stabilization.
Keep the trunk stable against the movement of the legs.
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 knees straight.
Objectives
Strengthens the adductors with focused, well-organized engagement.
Develops refined coordination and precise control when working against the springs.
Builds strong trunk and hip stability to counter the quick, dynamic movement of the legs.
Focus on breathing to synchronize the movement.
