How to run roller skating?

Lean forward, bend over, stretch out your arms boldly, push your legs hard to the ground, land with your feet alternately outside the figure of eight, and push the ground outward when landing. This is a starting action, that is, stomping hard and kicking outward. When we slide freely on the flat ground, we dare to make great efforts deliberately, and then this starting action comes out. Be sure to think boldly about kicking the ground. It may be unstable at first, but it will soon be practiced.
