It's interesting you should say that, Dan, because I know you're a fan of Gozo Shioda, and he really emphasised those elements in his teaching...
It doesn't matter that he said it. Alignment and whole body use is claimed in everything. Do you want to equate his work with TKD to boxing?
Of course not. Things are much deeper and have more meaning than that. I have never read anything really meaningful from Shioda or any other Japanese guy about what they do. Everything I have seen so far from a Japanese teacher is all but useless. I will leave it up to people to ask just why that is.
