Stand with feet shoulder-width apart
Put most of your weight on one foot
Keep the other foot flat and lightly touching the floor
Slide the weighted foot backward while keeping it flat
As the first foot moves back, shift weight onto it
Lift the other heel slightly and slide that foot backward
Repeat the alternating backward slide smoothly
Keep your upper body steady and relaxed
Bend your knees slightly
Stay on the balls of your feet when needed for balance
Practice slowly until the motion looks smooth
Increase speed only after the steps feel controlled
