Small belly is actually easy to lose, [I tried my method myself]. You get up in the morning and drink a glass of honey water on an empty stomach, and then eat at noon. If you are really hungry in the meantime, I suggest you have another cup of soybean milk or milk. Eating green food at noon is very afraid of being hungry. Of course, I still eat 2 liang of rice. I suggest that you eat less than usual every time you eat, so you don't have to eat very little. Dinner. !
You can do 30-40 sit-ups before going to bed. If you are interested, you can do a shoulder handstand and support it with a wall, and it will be OK.
The exercise of sitting on it can be aimed at a small belly. If you are always too lazy to do it, then stick to the above eating method, which is the whole body weight loss method.
