This man looks at people. It's ok if your weight base is relatively large. For example, if you used to weigh 300 pounds, it is really possible to lose 30 pounds after running for a month. If your original price is 150, it is almost impossible to reduce it to 120 within one month. In addition, losing 30 kilograms a month is too much, which is very harmful to your health. You should do it step by step, for example, about one month 10 kg, and stick to it for one and a half years, and the effect will be the best. . . .
