The human body craves alignment. When we are properly aligned, our bones, not our muscles, support our weight, reducing effort and strain. The big payoff with proper posture is that we feel healthier, have more energy, and move gracefully. So while the word "posture" may conjure up images of book-balancing charm-school girls, it is not just about standing up straight. It's about being aware of and connected to every part of your self.
