2 Medium Springs or
1 Light & 1 Medium Spring
Muscle Focus
Hip Extensors
Gluteus Maximus, Hamstrings
Resist the springs as the legs come toward the body.
Assist the hip adductors and hip external rotators to press the legs back out.
Don't overwork the glute and squeeze, focus on the hamstrings and the top of the thighs where it meets the hips.

Knee Extensors
Quadriceps Femoris: Rectus Femoris, Vastus Medialis, Vastus Intermedius, Vastus Lateralis
Resist the springs as the knee bends with control.
Straighten the knee as the legs extend.

Hip External Rotators
Gluteus Maximus, Piriformis, Obturator Internus, Gemellus Inferior, Gemellus Superior, Quadratus Femoris
Rotate the legs to turn out.
Assist with the hip adductors to close the legs.

Hip Adductors
Adductor Longus, Adductor Brevis, Adductor Magnus, Gracilis, Pectineus
Resist the springs as the legs.
Close the legs together.
Encourages the midline connection into the core.

Other Muscles at Play
Anterior & posterior spinal stabilizers provide lumbo-pelvic stabilization so the tailbone can stay anchored, keep the back from arching and ensure the pelvis doesn't tilt or rock side to side.
Hip abductors open the legs, though the adductors & hip extensors work harder to resist the springs.
Dorsiflexors flex the ankle as the knee bends.
Plantar flexors point the feet as the legs close together and on the leg that opens to the side straight.
Shoulder extensors press the arms firmly into the carriage to help stabilize the body.
Scapular depressors keep the shoulders down away from the ears.
Objectives
Enhance trunk stability by engaging deep abdominal muscles and simultaneously strengthen & stretch the hip muscles as the legs move in different patterns.
Emphasis is placed on abdominal control and pelvic stability as the legs are in motion.
Keep the arms strong alongside the body for support, maintaining a connection with the mid-back to help control the range of motion of the legs.
Keep even weight in both straps to prevent the legs from moving too wide or tilted, keeping the hips and trunk anchored evenly on the carriage to ensure trunk and pelvic stability.
Focus on breathing to synchronize the movement.
