Posture comes from Latin ponere which means to place or to put. So, a good posture is when your body just puts itself in place such that it gives you an optimum mechanical advantage.
The part of the body that deals with this mechanical vantage point or “good posture” is your skeletal system. So, if you have to engage your muscles to hold up your posture, you have spinal injures that need to be corrected.
