What is correct posture? What a loaded question!
Posture, is it the same for everybody? Yes, and no. That didn’t help a whole lot, did it? Yet please allow me to explain. Posture, defined by Merriam-Webster is a position of a person’s body when standing or sitting. Posture, defined by biomechanics is when the central nervous system, internal organs, brain and skeleton are stabilized and supported by the coordinated action of working musculature to obtain it’s segments aligned and maintained.
Posture starts at your feet and works its way up to your ear. As well, it starts at the head and works its way down to your feet. It also dissects you in half, creating a left side and a right using your belly button as the midline. Yet, let’s make this simple. If I was to ask you to stand up tall and give me your best posture, 9 times out of 10 you will be standing backwards of your midline.
