Do more aerobic exercise in the morning, stretch your muscles, eat high-protein and low-fat foods such as oatmeal for breakfast, and refrain from eating more at lunch. It is best to exercise for half an hour before meals in the afternoon, and go out for a walk after meals. Of course, you should also control your dinner, never eat midnight snack, swim or climb mountains at least once a week, often skip rope, sit-ups and push-ups, and it is best to do push-ups before going to bed. The number has been set for you. Until you know you can't add it, add one every three days, and so on. You'd better go to the gym to stretch and do aerobic exercise in the morning. If you can't afford it, do squats, leapfrog and sit-ups. The number is the same as push-ups at night. I used to do sports, so it's okay, but keep it up!
