I'm a beginner and reading the book Tao of WC. In our first class, we're of course learning Siu Nim Tao, I think it's called. Square stance, 50/50 weight on both feet. At some point do we go to a different stance? Like maybe left foot forward and 30% weight on front foot and 70% on back foot? That's what the book is talking about, being grounded and firm on the back foot, with the front foot able to fast front kick. Thanks. Sorry if this has been posted before, I didn't find it.
