Rule number: should hold, but not compress

"It is also important to take into account the size of the chest, since it is basic that the top supports, but does not compress. It is recommended that it fit but with comfort to allow freedom of movement", points out the Medical Specialist Doctor of women's sport. "The chest is an anatomical part in which discomfort and injuries can appear when practicing sports, and hence the importance of protecting it correctly. For example, running is an impact sport in which it is recommended that the breasts be securely fastened to minimize the risk of injury.

Cup bra, yes or no?

"It is recommended that both cups be differentiated, that is, that there is a central separation. In this way, each breast will be protected and unnecessary and uncomfortable displacements will be avoided. It is also important that there is the option of regulating the size both in the straps like on the back, for the contour. It is perfect that the cups are separated, but if the rest of the garment cannot be adjusted, the chest will not be completely protected".
