After running, you must do stretching exercises, as Ms. ZJ said. Don't stretch, sit down and rest immediately after running, and your legs will easily thicken. Running in situ, or jogging, belongs to aerobic exercise. In aerobic exercise, jogging is the most respected way for coaches to lose weight. If you can't insist, you can go quickly or combine walking and running. Let's just say it may be a bit of a blow. However, jogging can enhance our cardiopulmonary function. If you just want to thin your legs, you can do some thigh exercises after jogging, once 15, and you can do more than three groups. It is best to jog 15 minutes later (when the body is warm, the harm is less than when the body is cold, and the effect is better), and then continue jogging. Jogging is all over the body.
