People don't often say that Rhapsody in July is a flower, and the most successful is a man around 40 years old. They are in the rising or peak stage of their careers, and they are in their prime. However, I don't know that at the age of 40, a man's body is in a stage of decline, and there are often "three weak" symptoms. 40% aerobic exercise +60% muscle training, 60% aerobic exercise +40% light and moderate equipment training. In the whole training time, aerobic exercise accounts for 40% of the total training time, such as jogging for 40 minutes first; Coupled with muscle training, such as sit-ups and push-ups, 40-year-old men have more puffiness because of more entertainment and less exercise, and the most concentrated problem is in the waist and abdomen. You can do a self-test by hand and grasp the fat in the waist and abdomen. I'm all flaccid. Obviously, these are all fat.
