No, girls' fitness is good for breast growth. Proper exercise can help the development of chest muscles and improve chest lines. Women's breasts are mainly filled with fat and water, so if the muscle layer is developed, it will have an indirect breast enhancement effect, but you need to pay attention to the following points:

1, underwear must be worn.

Many women don't like to wear underwear when they exercise, but because there is no bone inside the female chest, they have certain mobility. If you don't wear underwear when you exercise, the internal tissues of the chest will flow with the movement of the human body, causing harm to the breasts, so you must wear a suitable sports bra when you exercise.

2. Don't diet too much.

Girls like dieting to lose weight, thinking that dieting while exercising will definitely have a good weight loss effect. Actually, it's not. When you exercise, you will consume a lot of fat in your body and have fat in your chest. Dieting can't provide enough nutrition for the chest, so it's not good for the chest. Especially for girls who want breast enhancement, you may mistakenly think that girls can't exercise, which will make your breasts smaller. However, the real reason is that when you exercise, you don't give your chest enough nutrition, which leads to your chest becoming smaller.

3. Don't exercise too much.

Girls should not do too much exercise for the first time. It is suggested to choose fitness programs and sports equipment suitable for you, and use the equipment accurately under the guidance of professionals to avoid muscle strain.

Personally, I think that female students' fitness is very beneficial to chest development, but we must pay attention to ways and means, don't rush for success, and pay attention to step by step. Only in this way can we have better results.
