I've been reading too many fanfics and am having trouble remembering which training methods and actual Martial arts training practices only get into Ranma 1/2 stories through Fannon. Such as Kata.
The thing is I would like sites with information on actual martial arts training practices that are more detailed than just what I could see shown in say the Karate Kid movies. I know they show basic Kata, specific move practice, and alternative movement training methods for blocks. But I intend to try to make a fic where the Anything Goes school can start out pure cannon and in the fic be evolve into something more real world traditional before the end.
So just in case I caused confusion I'd like to know what real world martial arts training things are only in Ranma Stories as fannon and links to (Preferably in english) sites with actual real world martial arts training tips and tools.
