Re: The "Jo Trick" and Similar Exercises
Looking over all this, I find myself wondering: what other Japanese martial arts focus on this stuff (internal strength / ki / kokyu / etc.)?
IIRC, either Ellis Amdur or Toby Threadgill mentioned there were a few Koryu, and there was a karate instructor at aiki-expo last year, and someone brought up something called taikiken in one of the earlier threads in this current ongoing discussion on the internal-ness of aikido. Seeing how that sentence is the limit of my knowledge, I'm curious: how frequently do other martial arts from Japan also discuss internal issues, or is aikido (relatively) unique in how much it focuses on ki & kokyu (if sometimes only in rhetoric)?
