Exercise your muscles step by step. Do less for the first time to warm up your body, or go jogging for ten minutes first, so that your whole body muscles can move and your bones and joints can be separated, which can avoid strain and joint sprain. Exercise is divided into several groups, such as the first group doing 5 times, the second group doing 10 times, and the third group doing 15 times. . . . Then feel a little tired, rest for 5 minutes, or do other exercises, then continue, and so on.
Exercise should be moderate and the amount of exercise should be scientifically distributed. According to my personal experience, as long as I don't get fat and keep practicing every day, I will have six abdominal muscles in a week. Try to practice moderately in the morning, noon and evening. Never stop, you will leave soon (if you like staying at home). It is best to take part in more sports, such as basketball and football, so as to keep the abdominal muscles well.
