At first glance these might appear to be completely unrelated topics, but they actually are.
The point being both stress stances, body positioning and body movement.
For example, when turning bowls and vessels I often find myself moving from say, front-stance to back-stance (and back), or from left-tiger to right-tiger. While I often find myself in a "natural" or horse stance when doing spindle work.
Watching demonstrators I can often tell, from the way they move, if they have any martial arts training.
