I believe you have also experienced rapid chest contraction or chest pain during short-term exercise. This is because the chest is not perfectly cared for during exercise, which leads to the pulling of ligaments and skin, which quietly damages your chest health. Sports bra is a category classified according to "the specific function of bra". Therefore, as the name implies, sports bra is to avoid chest injury during exercise and fitness. When running, jumping and other sports, the chest will shake and shake.
A healthy body comes from healthy exercise, but our breasts are gland organs hanging down from the pectoralis major, without the support of bones and muscles. When exercising, if you don't wear underwear, the vibration of your chest can easily lead to sagging breasts, which will affect your appearance and movements. You must wear it for a long time and do a lot of exercise. Because women's breasts are mainly composed of glandular tissue and fat (muscles can be ignored), they are fixed by ligaments. Excessive chest movement during exercise will make the breast shift and stretch, and long-term stretching will lead to irreparable sagging of the chest.
Excessive chest exercise will stretch the suspensory ligament of the breast and you will feel chest pain. Like elastic belt's overstretching, the hanging ligament of the breast can't recover its original elasticity after a long time, and it will be under the chest! Hang up! Foreign experiments have found that when the average person runs a mile (that is, 1609 meters), the breast will shake 135 meters. Even with a 34A cup, his breasts will leave his body 4.2 cm during exercise. A 36-year-old female, her chest jumped up and down about 1 1.9 cm during exercise.
