the psoas provides a diagonal support through the trunk, forming a shelf for the vital organs of the abdominal core. In walking, a healthy psoas moves freely and joins with a released diaphragm to continuously massage the spine as well as the organs, blood vessels, and nerves of the trunk. Working as a hydraulic pump, a freely moving psoas stimulates the flow of fluids throughout the body. A released, flowing psoas, combined with a stable, weight-bearing pelvis, contributes to the sensations of feeling grounded and centered.
And the circus of small abs movements begins! Enjoy and live longest!!!
