Don't worry, it won't. It's just that my thighs are congested after exercise. I will rest for a day or two. Long muscles are not as simple as people usually understand. Muscle growth will only increase after a long period of practice. General shaping exercise will only make the leg lines look better. If you are a woman, you don't have to worry about muscle growth, because muscle growth needs another important factor-androgen. Women's androgen secretion is about one-tenth that of men, so even if you train ten times as much as men, you may not grow muscles.
