This week on the Exercise Is Health podcast, Julie and Charlie discuss a predominant myth in the fitness world - the Magic Muscle Myth.  The idea behind the Magic Muscle is that there is one muscle that, if released, relaxed, or strengthened, will be the fix-all to ALL of your physical health issues.  Julie and Charlie discuss three of the most common muscles that are promoted in this manner - the psoas, the piriformis, and the rotator cuff muscles.
