Pects and Lats. For some reason I left PT school thinking the former moved your arm toward your chest and the latter helped you wipe yourself. Certainly functional, but not very exciting. Oh, and by the way they seem to get tight and keep shoulders in a forward rounded position-quite inconvenient. Then recently, I was in a Thomas Myer’s class on fascia and the instructor was going over the functional anatomy of these two muscles. They both do this funny little twist before they insert on the arm bone when it’s at your side. Weird thing for a muscle to do that’s trying to pull and exert force.
Write something about yourself. No need to be fancy, just an overview.
