Fascia is the connective tissue surrounding our muscles. As an example, fascia is the white film on raw chicken meat. Our muscles are also encased in fascia, as pictured below.
As a licensed massage therapist, I've seen cases where the fascia is so restricted that the lungs cannot fully expand to inhale.
Manual therapies like massage can help release fascial adhesions to allow greater range of motion throughout the body.
