Fantastic blog interview. I read the whole thing through just now. I was also wondering about the contraction being steady or explosive. Thanks a lot. Really useful extra info. From a yiquan point of view, it seems like this protocol should enhance shi li and "almost movement" right? Did you find these two exercises compatible? I only know some tai chi, no yiquan.
In case Dave ever logs on here again - thanks for the book - you gained another reader here on RSF, and your reader gained some useful knowledge and is putting it into action. I'm only on day 2, and my main issue now is "beginner's enthusiasm" - I feel like overdoing it a little bit.
