Put your feet together first, and then separate them by 5 cm.
Stand on tiptoe with your right foot
The tip of the right foot supports the ground and the center of gravity is on the right foot. The left foot feels free to move. At this time, the left foot must be moved backwards, and the left foot should be straight.
After the left foot moves backward, the left foot quickly stands on tiptoe, while the right foot is flat, which is equivalent to the starting action.
Focus on your left foot, translate your right foot backwards and keep it straight.
Repeat step 1-4, and repeat this step to see the effect.
Matters needing attention
To prepare your feet, stretch them first.
Practice, beginners can find a smooth plane to practice, or sprinkle some talcum powder on the tile to reduce friction. After practicing the effect on the shiny surface, they can practice on the rough surface. When practicing rough plane, the left and right feet can be translated at a long distance without touching the ground, as long as the effect is good, people can't see the flaw.
