Stand up straight and ensure you have a clear route behind you.
Imagine a straight line on the floor extending away from you, or place a straight line of tape along the floor.
Walk backwards along this line on the floor as if you are walking a tightrope.
Place one foot behind the other foot so that your toes are touching the heel.
Try to maintain your balance and keep your feet stepping in the middle of the line.
Make sure you do not allow your posture to stoop.
