Running to lose weight is feasible, but it can't be said that losing your stomach means losing your stomach. partial weight loss can't lose weight! Since running can lose weight, it means reducing body fat and reducing the percentage of fat, which is the body fat rate of people. Once the body fat rate comes down, the whole person looks thin, and then the stomach is gone! But I suggest not only running, but also some strength training, such as sit-ups and push-ups. The effect of slimming will be better.
