Running in situ can lose weight, but only for a certain period of time. Generally speaking, aerobic exercise is slow to lose weight. Therefore, when we run in situ, it takes more than half an hour to achieve the goal of losing weight, because often the sweat in the body is eliminated within half an hour. Even if you see weight loss, it is often water in your thin body. After half an hour of exercise, the fat in our bodies began to burn.
