The Fuzz Written by Calvin Sun Most movement issues we see are due to what most people describe as muscle “stiffness” and/or “tightness.” In reality, your muscles are really numerous sliding surfaces built upon more sliding surfaces. Often problems arise when these surfaces no longer slide very well. Take a look at the photo above, see the cobweb-like structures on both sides? That is fuzz that has accumulated in between tissue surfaces. “Fuzz” is almost like an adhesive in that it causes your sliding surfaces to stick together as if they were glued down. This can result in poor positioning, diminished force production, and tends to rob you of maximal efficiency and performance. Even worse, you can put yourself on the fast track to injury if you let your untamed fuzz accumulate. You probably didn’t know it, but you are a fuzz making machine. Dr. Gil Hedley explains further in this video (just a warning, it does contain images of human cadavers so don’t watch if that kind of thing bothers you or if you are reading this while eating your lunch).
