How far does the skateboard go?

You're talking about the manual in the skateboard, which is the rear wheel balance. In fact, this movement is easy to practice, and it is not easy to practice well. The main thing is to find the center of gravity that suits you. First of all, put the front foot near the screw, you can use a certain angle, and step on the back foot in the middle of the board tail. Don't tilt it, or it will fall to the ground in a short time. Keep your arms as straight as possible, relax your body and breathe calmly. Take your time. The front legs should be slightly bent. The center of gravity is between the legs. It takes more practice to practice this well. Then you can practice nose manual. Good luck.
