When running, the legs don't get thicker, but the muscles are tight. The correct way to lose weight is this: it is best to jog so that you can lose more fat. The running time is 40 minutes to an hour. It is best to run in the park at night and not to exercise in the morning. After running home, do stretching exercises, such as starting from both ends of the waist, leg press, and doing sit-ups. Only in this way can we keep fit and lose weight. There is also the need to persist, more than three times a week.
