Fascia & Muscle work together. Without fascia, muscles would just sag and hang. But with fascia the muscles take their shape and interact with other nearby muscles. Follow along as Shaun Walker describes what may be the most important “anatomy train”, The Spiral Line. He will step through the actions of the muscles that are crossed by the spiral line and how they interact with each other. These muscle interactions are critical to efficient movement. This presentation will change how you approach training your pitchers.
