Bruce Lee famously said "be formless, be shapeless, be like water," and that type of thought is exactly why Sensei Russell George was first attracted to the martial art of Bujinkan Taijutsu. George says this style of self-defense flows more and is less rigid than other martial arts he first tried.
Bujinkan Taijutsu originated in Japan and is over 900-years-old. What's appealing about this style of martial arts is the ability to teach it to people of all ages and all body types, as it uses a lot of the opponents weight against them. The Temple arm visits Japan each year to train with Sensei Hatsumi who has been a martial arts consultant on two James Bond films.
The ability to learn self-control is the main part of Bujinkan teachings and when to defend and when to walk away.
