here's how to predict whether or not your friend will lose breast size:
if she is a thinner girl with large breasts, and especially if large breasts run in her family, then the majority of her breasts are most likely made up of breast tissue, and not fat, so exercise will not greatly affect them.
on the other hand, if she is a heavier girl, there is a much better chance that exercise will cause her to lose inches off her chest.
