Gil Hedley’s Fuzz Speech: How Connective Tissue Adhesions Impact Mobility

In this classic presentation, anatomist Gil Hedley uses a cadaver demonstration to explain how connective tissue, which he colloquially calls “fuzz,” continuously builds up between muscles. He describes how overnight rest creates light tissue adhesions that naturally melt away during morning stretches and everyday movement, keeping sliding muscle surfaces smooth and mobile. However, when movement is avoided due to injury, pain, or a sedentary lifestyle, this tissue thickens over time, progressively restricting full range of motion. Hedley emphasizes that consistent daily stretching and hands-on bodywork are essential to breaking up accumulated adhesions, preventing stiffness, and maintaining long-term mobility.
