Fascia as defined:
A sheet or net of fibrous tissue that envelops the body beneath the skin; it also encloses muscles and groups of muscles and separates their several layers or groups. Fascia is made up primarily of densely packed collagen fibers that create a full body system of sheets, chords and bags that wrap, divide and permeate every one of your muscles, bones, nerves, blood vessels and organs.
In fact, there are very few things in the body that are not wrapped by fascia. Fascia can easily be thought of as the largest, soft-tissue structure in the body but has long since been the structure we know the least about. Some strides have been made in fascial research during the last 20 years or so, but it is still largely ignored and underestimated in much of the healthcare field. Fascia is not a traditional body system like our circulatory, nervous system and others, but it interacts with all the systems in the body making it extraordinarily unique. And unlike other areas of the body, there is no medication that can improve your fascia, no supplement that can optimize it and exercise alone does not optimally balance, align or improve your fascia.
