Wall Bend

Have you ever tried to stand straight against a wall, then try to pick something up from the floor in front of you without letting your legs leave the wall? If you have, you will notice this is not possible. The reason that this isn't possible is due to something called "Center of Gravity". Your center of gravity can change when you make different positions and when you are either rapidly moving or dancing. When your body is standing straight against the wall, your center of gravity lies in your lower abdomen. As you bend over, your center of gravity shifts from your lower abdomen to the outside of your body, located right outside your stomach. Due to this shift of gravity your body loses it's balance and you fall or stumble to regain your balance.
