When I was doing my standing meditation today I felt a stretch inside the right part of what I think is the shoulder cavity. When I was putting my attention on that area sometimes it would move and I would notice that there was some kind of random bubbling or pulling sensation that would only happen for a moment on the inner back near the shoulder blade. The type of stretch feeling in the shoulder cavity feels like the kind of push pull feeling in the feet or in the pelvic like the transverse stretch.

I've noticed my feet naturally supinate while standing. When I straighten them out, it produces stretching around the inside of my knee. I'm wondering what is the best way to address this or if I should allow the supination.

When practicing the back slap bear slap I was feeling a stretch in my lower abs on the side of the body that I was stepping towards while twisting the hips before the front of the chest moves. I don't think I had ever noticed this before and/or maybe I'm doing it differently now. Is this part of what we want to feel when doing this exercise?
