If the normal abdominal pants are not a big problem, the tightness should not be too high otherwise they will strangle themselves and easily cause poor blood circulation, skeletal deformation, compression of the abdomen, affecting gynecology and other conditions. It is best to choose the abdominal pants to be comfortable. If you want to achieve the effect of weight loss or shaping, it is unlikely. Weight loss or shaping must be achieved only through exercise or liposuction surgery. After exercise, you can consider wearing some comfortable abdominal pants for shaping, which takes a longer time and the effect varies from person to person.
