Lose fat first, then exercise. You can run for about 40 minutes every day, at least half an hour, more than 6 kilometers. Do leg stretching after running. Then don't eat snacks and eat reasonably. Then do sit-ups and sit in groups every day, 30 in each group, and do 3 groups. You can increase it later. Rest between each group 1 min, which can be used for abdominal stretching, lying on the ground with the front face, then propping up with both hands, relaxing the waist, relaxing the whole body, propping up with one arm and leaning back the head, which can alleviate abdominal distension the next day.
