Join us for another Vault Classic. In this episode Scott Johnston is joined by Phil Maffetone to discuss the nuances of Over Training. Over Training is not your garden variety fatigue that a few days of rest will overcome.  It is a medical condition that is misunderstood by most athletes, coaches and medical professionals.  It's difficult to diagnose and harder to treat.  In this episode Phil and Scott discuss diagnosis and treatment as well as strategies to avoid this elephant in the endurance training room that will keep you from falling off the Over Training cliff. Listen for guidance and tips for how to avoid this.
