Stand with your feet shoulder-width apart
Put most of your weight on one foot
Keep the other foot light and ready to slide
Lift the heel of the weighted foot slightly
Slide the lighter foot backward smoothly
As the sliding foot lands flat, shift weight onto it
Lift the heel of the other foot
Slide that foot backward in the same way
Alternate feet in a smooth, continuous motion
Keep your upper body steady and relaxed
Bend your knees slightly
Stay on the balls of your feet when possible
Practice the sliding motion slowly first
Increase speed only after the movement feels smooth
