Seriously, it's useless. If you are growing up, it is especially bad for your health, because it will only tighten your stomach, put a burden on your respiratory and circulatory system, and will not burn fat. If it really works, it's also because you eat less after girding your waist.

In the history of Europe, women once tied their waists crazily, which really made everyone's waists thinner, but at the cost of internal organs being oppressed and gastrointestinal function declining.

So don't try without the determination and physical condition to suffocate yourself.
