Do you practice long-distance running every day, and your calves and thighs won't get thicker? Stick to it for a long time and it won't get thicker. It may be that the running time is short, and the muscles caused will make you feel that the calf is thicker and the thigh is a difficult part to exercise.

If you want to lose weight, you should exercise for at least 40 minutes at a time, preferably aerobic exercise (jogging, mountain climbing, swimming, etc. If you don't want to spend so much time, you can do some strenuous activities before jogging, such as leg lifts, squats, squats, jumps, etc. There is no absolutely correct posture, as long as it suits you, as long as it doesn't hurt your back and legs every day. Of course, long-term weight-bearing will affect height, but proper exercise stimulation is good for height. Relax after running every time, and you can swing your legs and jump.
