Let's take a look at the answer to this question first: scientific and reasonable fitness will not only make girls become airports, but also make their breasts look better! Usually, the factors that affect the size of a woman's breasts mainly include family inheritance, environmental factors and hormone levels in the body. Family inheritance is determined by innate genes and cannot be changed the day after tomorrow; Environmental factors mainly refer to the living and growing environment; The hormone level in the body is affected by the physical condition and can be improved by the acquired conditioning.
I think many people have the misunderstanding that "fitness will lead to girls' airports", which is mainly influenced by the image of some thin athletes, and think that fitness will lead to airports. I think these athletes are born with small breasts, and high-intensity training leads to low estrogen levels. Long-term high-intensity training leads to low body fat and tight sportswear. But ordinary girls don't have to worry, because the usual fitness training intensity is far less than that of professional athletes, which will not lead to too low body fat, and will not lead to too low estrogen level. This kind of worry is unnecessary.
On the contrary, girls who are dissatisfied with their breasts can also make their breasts fuller and better-looking through scientific training. In fact, girls also have pectoral muscles, but they are usually hidden under their breasts because they are not big enough to be easily seen and ignored. Specific training actions include bench press, supine bird, chest push, fitness ball push-ups and so on. Supine birds, 3 ~ 4 groups each time, each group 12 ~ 18 times; Push the chest while sitting, 3 ~ 4 groups each time, each group 12 ~ 18 times; Fitness ball push-ups, 3 to 4 groups each time, each group 12 to 18 times; Dumbbell bench press, 3 to 4 groups each time, each group 12 to 18 times; Women should not do too much aerobic exercise in fitness training, and the intensity should not be too high, so as not to lead to low body fat and low estrogen level. Nutrition should also be balanced, and the intake of protein and vitamins can be appropriately increased.
