'Arwrology' is derived from the old Welsh and means an all-out hand-to-hand fighter: it was developed by Gordon Perrigard, a Canadian medical doctor who blends advanced ju-jitsu with human anatomy insights. Chapters show how to defeat an armed person, overcome brute strength, and fall without injury. Learn all the basics of hand-to-hand combat in a fine survey that includes black and white step-by-step photos.
