Imagine wearing a medium weave body sweater and socks.  Imagine moving inside a sweater and how it slides over your body as you do so.  If however, there is a tear or a place that has been darned or if the sweater has been pulled out of shape, the sweater will not slide over the body as easily.  Nor will it hang the same or maintain its shape.  The sweater has been pulled or mended out of form.

The point of this is that we are basically wearing a sweater made up of connective tissue that moves over the bones and muscles and in which the muscles can work and the bones can align.

The purpose is to have the fascia (sweater) aligned again to attain that smooth movement capability, ease of movement and maintaining a beautiful shape.
