Re: A word on Time Trained and Ranking
David, I think you are misunderstanding. Chris' use of "aggressive posture" is not to say kamae is aggressive but as a usage example that the term kamae refers to a specific English usage of the word posture, which does encompass multiple meanings - in this case assuming a stance.
Posture also refers to an inherent structure - when I am in kamae, when I sit at my desk or walk down the street there is how everything hangs together - the stuff I'm working on changing my getting Rolfed.
Theoretically one can have lovely posture and lousy kamae and vice versa (having in mind a skilled martial artist with a skeletal defect).
