Stand with your feet together and your knees slightly bent
Put most of your weight on one foot
Slide the other foot straight back while keeping it flat on the floor
As the back foot slides, shift your weight onto it
Lift the front foot slightly and let it glide back to meet the other foot
Repeat the sliding motion smoothly and continuously
Keep your upper body relaxed and mostly still
Stay on the balls of your feet when needed for balance
Practice slow, controlled weight shifts
Increase speed only after the motion feels smooth
Use a mirror to check your form
Practice regularly until the movement looks fluid
