Running is divided into aerobic running and anaerobic running. Aerobic running is jogging. You can see how thin those marathon runners are. Anaerobic running is to increase muscles. According to sprinters, they are all muscular! Secondly, the duration of exercise is more than 40 minutes, because the first 30 minutes only consume sugar, not fat, and the best weight loss effect is more than 40 minutes. So all you have to do is jog for a long time, and you will lose weight if you don't gain muscle.
