44 y.o. ques re: mushroom circle

Hello, I have a question that sounds stupid but I think it is important that I be able to have my body 100 percent correct to learn the circles and become as good at them as possible. So my question is: when doing circles on the mushroom should your glutes (butt cheeks) be sort of pinched together as your feet are extended away from your body or instead just extend your feet and keep the feet together as you go around with no need to have your butt squeezed????? I know it sounds dumb but I'm wondering about the proper procedure.... thanks, Kevin

Squeeze your cheeks.
