As you say, you'd better walk slowly. Walk for 4.5 hours every day. I believe that the leg beauty effect is very obvious. Secondly, jogging. Generally, the jogging time is at least 20 minutes, but you must pay attention to relaxation to prevent lactic acid accumulation. In addition, you can only stand and swing your legs for half an hour after running. The effect is quick but bitter. It is recommended to climb stairs. It is also a good way to beautify your legs!
