First we should what is fascia?
Fascia is a layer of fibrous connective tissue that wraps our muscles. It is divided into deep fascia and superficial fascia. Simply put, it is the layer of chewy tendons when we eat beef. We can think of the fascia as a spider web. When a thread is drawn, other parts will also change. Therefore, physical exercise rehabilitation that considers symptoms from a fascia perspective often requires a holistic view, rather than where the pain is where the fascia gun hits. When the fascia appears with muscle spasm, wrong position, adhesion contracture, there will be a series of pain, function limitation symptoms, etc. Therefore, relaxation of the fascia is sometimes necessary for physical exercise rehabilitation, but not absolute , and it is not that fascia is considered for all problems encountered.

After understanding what fascia is, we can better understand how the fascia gun uses the principle of muscle resonance to exert force on the fascia, and thereby achieve the purpose of relaxing the muscle: the fascia gun first acts on the surface of the muscle Under the dual action of physical stimulation and muscle warming, the elastic extensibility of the muscle fascia will increase. The fascia gun uses this principle to relax the muscles of the body.
