Because of your lack of exercise in the past, your body can't adapt to strong exercise for the time being. If you choose to run away. Pay attention to let the body adapt slowly. It is recommended that you walk fast for two or three laps along the runway (400m), and then jog for three or five laps. The time can be relaxed for 30-40 minutes. But only if you insist on it every day! It's no use fishing for three days and drying the net for two days! You can follow the above steps and try to improve the intensity within three or four months, depending on your personal situation. But remember to stick to it! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
