Is there any way for a girl to have an athletic body without losing too much breast tissue?

most athletic girls I see are flat chested but they got great bodies.
they look like their breast are turning into mens pecs
I have seen some girls with big breast and athletic bodies but thought those where fake breasts

so is there any way for a girl to have both natural big breast and an athletic body?
