Answer:
Bear your weight primarily on the balls of your feet.
Keep your knees slightly bent.
Keep your feet about shoulder-width apart.
Let your arms hang naturally down the sides of the body.
Stand straight and tall with your shoulders pulled backward.
Tuck your stomach in.
Keep your head level-your earlobes should be in line with your shoulders. Do not push your head forward, backward, or to the side.
Shift your weight from your toes to your heels, or one foot to the other, if you have to stand for a long time.
