Understanding the topography of the human body is essential to knowing
how each posture works to enhance various bodily functions. Stretching
the muscles is a form of external massage that releases essential feel-good
juices and endorphins; while compacting of glands and organs is like an
internal massage that enhances gland and organ function.
Most glands and organs are located between the hip and the head, not in
the upper or lower extremities (arms or legs). So In order to ensure a total
body workout, it is vital to move the whole body, not just the arms or legs.
Because it is in the coordinated stretching of muscles and massaging of
glands and organs that we find our full release.
