Plane of Motion

Sagittal, Coronal & Transverse

Spring Setting

Light

1 Extra Light Spring or

1 Light Spring

Muscle Focus

Hip Adductors

Adductor Longus, Adductor Brevis, Adductor Magnus, Gracilis, Pectineus

Resists the light weight of the carriage to control the legs opening.
Keeps the carriage still as the spine moves.
Pulls the carriage closed.

Spinal Rotators

External Oblique (opposite side), Internal Oblique (same side), Erector Spinae (same side), Semispinalis (opposite side), Deep Posterior Spinal Group (opposite side)

Twists the spine.

Spinal Flexors

Rectus Abdominis, External Oblique, Internal Oblique

Rolls the spine down in flexion in rotation to reach opposite hand to foot.
Co-contracts with the spinal extensors on the roll up to support and control the articulation.

Spinal Extensors

Erector Spinae, Semispinalis, Deep Posterior Spinal Group

Stacks the spine back up to neutral in rotation.
Co-contracts with the spinal flexors on the roll down to support and control the articulation.

Other Muscles at Play

Anterior & posterior spinal stabilizers provide lumbo-pelvic & spinal stabilization.
Hip extensors assist the spinal stabilizers with the lumbo-pelvic stabilization.
Knee extensors keep the knees straight.
Shoulder abductors resist gravity and keep the arms elevated in a T.
Scapular depressors keep the shoulders down away from the ears.

Objectives

Enhance the strength of the hip adductors and stabilize the pelvis during standing movements and spinal rotation and articulation.
Enhance deep abdominal control and lumbo-pelvic stabilization to rotate and articulate the spine as the hip adductors keep the carriage from moving.
Keep the pelvis stable while engaging the obliques to rotate the trunk.
Extend and engage the hamstring connection while bending over and maintaining stability and control.
Challenges balance and stability while standing on the moving carriage.
Focus on breathing to synchronize the movement.
