I live in the "Sun Belt" but now that we are moving into mid September the temperature plummeted to 109° (43°C) today and will be dropping down into the mid 80s tonight in the pre-dawn hours. Needless to say, around here we wear very light clothing year round unless there is really freaky weather. I don't even own a heavy coat. So I've always worked out in a T-shirt and shorts or light, loose kung fu pants. Since Southern China is also a warm climate, light attire is traditional. Still, for those of you that live in cooler regions, how does wearing heavy clothing affect your WC technique and practice?
