It is normal to sit down and have fat on your stomach, especially for women. Women have more belly fat than men. If you run, you can lose weight, but if you are already very thin, the effect will not be too obvious, because the cells there are stretched and relaxed, so you must do some strength training to achieve the purpose of shaping your abdomen, such as the upgraded sit-ups: lie flat, don't press your feet with anything, and then put your hands behind your head. Lift your upper body with abdominal strength, but pay attention to stop at an angle of about 30-45 degrees when you get up. It is best to stand still for 5 seconds, then lie down and pay attention to breathing evenly during the process. In this way, as long as you do 30 exercises every day, you can help exercise your abdominal muscles. If you just follow the previous ordinary sit-ups, the effect will not be too great.

Besides, it's really hard to lose face, because it's a matter of face. You said it yourself, it's actually very thin but its face is a little fat. This is a natural face problem. In fact, a face with a little baby fat is quite cute. You can make her cute and beautiful with a proper hairstyle. Don't worry.
