It's normal, even good, to have different leg sizes. I practice track and field all-around, with 3 thighs and 2 calves, which is smaller than yours. However, the greater this ratio is within the normal range, the better it is for exercise. Of course, you are within the normal range, and you have to worry about being as thick as your thighs and calves. If your thighs are full of fat, do more aerobic exercise, such as running, swimming and skipping rope. Pay attention to control the intensity and ensure the time when exercising. Exercise time is the natural enemy of fat. If you don't have patience and exercise hard at once, you will grow a big muscle. Pay attention to relaxation after exercise, and muscles are not easy to agglomerate. And full-body exercise can make your upper body stronger and your body more symmetrical. There is also the need to ensure a reasonable diet, your upper body is so thin. If you do muscles in your thigh, do more relaxation massage to make it stretch and elastic, which will look good. It is not recommended to lose muscle in an abnormal way.
