Not necessarily? Losing weight should be a long-term low-intensity aerobic exercise, such as jogging, which takes time (muscle glycogen is the main energy supply before aerobic exercise 15 minutes, and fat energy supply starts after 15-20 minutes, so aerobic exercise is generally required to last for more than 30 minutes).

If you run hard, your thigh and calf muscles will be trained to be very masculine.

I have been insisting on long-distance running before, and I feel that running has limited effect on losing weight. My calves and thighs are not thin, and even I feel thicker and harder, and my muscles have taken shape. But I'm a man, and I like it. Weight loss must also be combined with diet control, so that the intake of calories is less than the consumption of calories, but not excessive dieting.
