Ju-jutsu (or jiu-jitsu) is translated from Japanese as "soft technique." This is an old martial art of samurai, the main principle of which is expressed in the famous phrase: "succumb to win!" For more than 300 years, the art of jujutsu has been kept secret from outsiders. Only in the 20th century was it opened for widespread study. But even today there are almost no good ju-jutsu benefits outside Japan. This workbook is one of the exceptions.
