Moving Parts

When you walk your entire body moves with every step. Muscles pull bones and joints bend. Your legs swing forward your toes bend and straighten your arms swing and your spine flexes your eyes move to check the ground under your feet the ground a few steps ahead and the scenery around you. If you see something interesting your head will turn to check it out. Your eyes quickly face front again so you don't trip over something.

Your weight automatically shifts to the second foot.
