In no other sport can mere brute strength be so quickly and so decisively overcome by sheer skill as in Judo-the modern, scientific form of Jiu-Jitsu. This practical guide will enable any physically normal person, practising with reasonable diligence, to develop in a short time the speed and finesse necessary for mastering the science of Jiu-Jitsu. Judo is also splendid as a day-by-day method for keeping fit as well as valuable equipment for self-defense. Systematic practice of the 120 Judo movements set forth by the authors is guaranteed to give tone to any sluggish muscle. Each step in the forty-one lessons in elementary Judo is clearly explained, with 180 illustrations of the performance in action. A glance at the accompanying direction gives an accurate explanation of the principles of leverage, balance and action that enable even a beginner to develop an undeniable advantage over any opponent. In this ENLARGED EDITION important new material has been added, including eleven lessons which will be of particular use to men in the armed forces. These movements are intended both for recreation and for use in actual hand-to-hand combat.
