Ribs play an important role in the stability of the upper part of the spine. Everted ribs will make the whole chest protrude forward. For example, your chest was originally 75C, but it may become 90C, and the whole lower bust will become larger, as if there were four boobs. Moreover, the everted ribs will skew the normal working position of the diaphragm and your breathing quality will be worse. For a singer or broadcast host, it will limit his vocal effect. If you want to improve this situation, you can go to a professional sports orthopedic research center for correction.
