When walking most of us just walk.  We don’t think that much about it, pay attention to our posture, and frequently take our surroundings for granted.   For many walking is mostly free time.   And free time often equates to relaxation.  So most of the time most of us walk more or less relaxed.   While relaxation is a good thing just like anything else if it occurs in excess bad things can come with it.  If our walking is too relaxed, for too long, bad habits can develop.  Slouching while walking can cause tightness in the front of the hips and a collapse of the chest and shoulders.    Not only does flexibility decline, weakness also develops, especially in the back and hips. If this posture persists long enough neck, back, hip and shoulder pain can also occur.   Believe it not the way we hold ourselves when we walk projects to others how and what we feel about ourselves; it also suggests to the outside word how they should feel and react to us. If you were to walk as if someone was pushing you from behind  the natural instinct would b to straighten up.  You would hold your head up, tighten your glutes (your butt muscles), and stand straight.  If you continued to walk as if someone was pushing you from behind you  then awareness of your surroundings and your self esteem would increase too.   Muscle strength, tone, and endurance would all get better.  Over time so would flexibility.   Walk like someone is pushing you.  Its good for your health!
