5. Breasts Move 8 Inches During Running
When a woman runs, her breasts move in a figure-eight shape that can cause breasts to shift up to eight inches while you move. Because they are not just bouncing up and down, a sports bra with individual cups is the best way to support breasts during exercise.
Fun fact: More than 49,500 people search for “bouncing boobs” per month on Google.
