The whole breast is attached to the pectoralis major muscle without bone support. Therefore, if the pectoralis major muscle is more powerful, it will help to maintain the shape of the breast-women who always feel that their chest shape is not ideal can pay more attention to the strength training for the pectoralis major muscle.

When the breast is moving, it will not only move up and down, but also shake in a figure of eight because of lack of self-support. Tracking the dynamics of women's breasts during running, the maximum jumping amplitude of breasts above 75C cup can reach 14cm during strenuous exercise, and even 75A, the vibration amplitude can reach 4cm. Every time you run 1.6km, the moving distance of the breast can reach134 m. Compared with the dynamic situation of wearing a cup-type sports bra, the sports bra can control the shaking amplitude within a conventional 8-shaped range even if it can't completely block the breast, which can reduce the shaking amplitude and avoid discomfort and possible injury caused by excessive shaking. Speaking of which, I have to mention the headline in the British Daily Mirror a few years ago: Madonna was seen wearing three bras for a morning run in Hyde Park, England. Women probably understand the importance of wearing a sports bra when exercising! "Ma Jun" originated from "Mermaid line VS vest line", symbolizing a beautiful figure and a healthy lifestyle.
