Your goal is to find a bra that supports your breasts and minimizes breast movement during exercise. The stretchier the material, the less support it provides. Find your size Use your regular bra size as a starting point, but since sports bras fit more snugly, you should try on several sizes, styles and brands. Look for bras shaped like your body. If breast tissue spills over the sides or out the top of the bra, you're wearing the wrong size.
Some companies make hybrid bras that incorporate molded cups into a pullover design.
Put your bra to the test My testing criteria were simple. I just didn't want my breasts bouncing when I exercised. All of the bras fit me differently and provided different kinds of support, so it didn't make sense to rank them, and I really couldn't decide on a favorite. Instead, I've listed the bras that worked for me in my activities. It took me awhile to get used to the fit, but I had a virtually bounce-free run.
