Stand against the wall. It works. I just sit in front of the computer all the time. As a result, my legs became thicker after a long time. Later, my classmates who had a good relationship with me told me that when she was doing physical training [she was an amateur model], the training teacher told her to stand against the wall, and she stood in high heels. The method of standing against the wall really made her legs thinner: let her shoulders [shoulder blades], hips and calves lean against the wall at the same time, hold her chest out and abdomen in. Standing in high heels is not recommended, but there is an alternative. You can tilt your heels, but standing in front of your feet will hurt for a while. If you want to stay still, you can stand for 10- 15 minutes at first, and then accumulate bit by bit. Because in the process of standing, the legs are always in a tight state. So you stand sweating all over, and your back is the most obvious, just like spraying with a watering can. At first, it will be very uncomfortable to touch the wall with your whole foot. The standard I set for myself is 20 minutes, because my calf can't stand against the wall naturally, and I will only lean against the wall if I work hard. Later, I raised my heel and stood [because I don't have high heels, so I used this method instead], until one day, my whole foot landed against the wall, my legs didn't have to exert any force, and my calves naturally leaned against the wall ... although this method was a bit painful. However, if we persist, there will be obvious effects. If you simply increase the amount of exercise, once you don't persist, the rebound will be very strong and you will be fatter than the useless exercise before. Plastic wrap is not for everyone. Although it can make your skin sweat in a sealed state, the sweat will not evaporate, and it is easy to irritate the skin after long-term use. If your skin is sensitive, it's very troublesome.
