This week I sat down with Dr. Jonathan Sum, a Physical Therapist who currently works at the University of Southern California in their division of musician rehabilitation. In addition to his vast knowledge of Sports Medicine and work with Major League players, Dr. Sum enjoys playing the guitar in his free time which has prompted his interest into why musicians don't adhere to similar training routines as top athletes even though our bodies are being asked to perform athletic feats.
