Run for at least 25 minutes every day and try to challenge your physical potential again and again with the fastest speed. If you want to be thin, you can only achieve your goal by consuming far more calories than you consume. Then, I will practice assistive devices, and finally do sit-ups to strengthen my abdominal muscles. At first, it was estimated that the landlord could only do ordinary sit-ups. When you are strong, you can do leg lifting, abdominal muscle rolling and so on. You can't see the effect of exercise overnight. The important thing is to persevere. Don't weigh it if it's okay. Stick to it for half a year first.
