In this new 138-page book, Black Belt Hall of Famer and 10th degree George Kirby discusses effective ways you can apply the fighting methods of traditional Japanese jujitsu to any martial art with an eye on street defense. There's a difference, Kirby argues, between being able to do a beautiful martial arts form and actually using that knowledge in a real-life situation. Self-defense requires movements that are extremely effective in their simplicity. However, acquiring that simplicity takes patience — which is why martial arts practice is a lifelong pursuit for so many people.
