Do not you have to wear a chest without sports bra?

Does every woman need a sports bra?
The answer is extremely positive.
Some people may think, "Oh, no, I'm a cup (or B cup) girl, I do not need to wear a sports bra."
This is wrong understanding. Even if A cup of women, during exercise, the chest will have a vibration amplitude of 4 cm up and down. The greater the size of the chest, the greater the vibration amplitude, G-Cup women's chest movement during exercise amplitude may be as high as 14 cm. What is the concept of 14 cm?

Female breasts are in fact the body of the body without the slightest muscle organs, do not like being Britain upside down. If repeatedly shaken without special protection, its ligaments are extremely susceptible to damage. The chest ligament if really hurt, not only can no longer be repaired, it can not be strengthened through the exercise, ruined it really ruined. (Do not put my own Mimi like this?)
Let us look at a set of three-dimensional simulation of the movement contrast:

健身不穿运动文胸 你还要不要胸了?


(Not wearing bra) shaking violently

健身不穿运动文胸 你还要不要胸了?
(Ordinary bra) shaking big

健身不穿运动文胸 你还要不要胸了?
(Sports bra) range is small

Data show: 75C breasts above the cup, in the intense movement of jumping up to 14cm, even 75A can reach 4cm vibration amplitude. Every 1.6 kilometers, breasts move distance is 134 meters. Imagine your rabbit moves 134 meters and you have a lot of thoughts?
