The body circumference has become smaller, but the weight loss is not great. This is a typical performance of primary dieters more than ten weeks before aerobic exercise. It shows that your weight loss has achieved initial results. In the early days of losing weight, in fact, every exercise will consume fat. In other words, theoretically, your weight should always be in the process of losing weight. But why stay the same? The reason is that your muscles are weak because you don't exercise for a long time. In the early stage of losing weight, your muscles will grow properly in order to adapt to the intensity of exercise. So gain muscle, lose fat, and the weight is close to conservation.
