Hello, the recommended answer is very detailed, but this is the law of abdominal muscle exercise, not the law of fat loss. First of all, I can tell you clearly that it is impossible to lose abdominal fat simply by doing sit-ups, or your waist circumference may decrease 1~2 cm after you work hard for half a year.

Jogging three times a week for 45~90 minutes each time, plus gym equipment training and controlling your diet and sleep rules, plus sit-ups, are the ways to lose abdominal fat and excess body fat.
