Start with your knees bent. They should be bent comfortably so that you can hold it while still keeping good posture. Do not stick your backside out or look like you are trying to sit down—there should be a relatively straight line that runs from your shoulder through your hip and down to the middle of your standing foot.
Push off your right leg, sliding your left foot across the floor and landing on the heel first when you step forward on count one, and then roll onto the ball of your foot. Your knees should still be bent the same amount as when you started.
Step to the side on the ball of your foot on count two. Your knees should still be bent at this point.
Bring your left foot to your right on count three, stretching yourself tall and straightening your knees until they are slightly flexed, nearly straight but not locked. You are on both toes for a moment, and then flex your knees and lower your left heel only.
Slide your right foot across the floor as you step back on count four, and then lower the heel. Both knees are bent.
Step on the ball of your left foot with both knees bent when you step to the side on count five.
Bring your right foot to your left on count six, stretching yourself tall and straightening your knees until they are slightly flexed, nearly straight but not locked. You are on both toes for a moment, and then flex your knees and lower your right heel only.
