This is useless. I used several pieces and threw them away. There is no patent application at all, and it is fake, and the patent office can't find it. I think this exercise is reliable. Although I joined many clubs in college, I was busy, but later I unlocked all kinds of exercise time and places, such as finishing my homework at noon and before dinner, such as the open space in front of the staff residential area of the riverside school, where fewer people went, and there were also horizontal bars and some equipment. I have more time at night!
The general content is the exercises that Yang Yunfeng did in his diary. He ran/kloc-0.000 meters, jumped 250 times, kicked 200 times, touched the height 50 times and walked 200 meters to relax. It's almost seven months now, and with the holidays, it's grown by 4 centimeters. I am 2 1. In fact, time is not too long to pursue sports. In a word, I regret not being as early as opening a new world.
