Why do my breasts hurt when I’m running?
The pain is probably caused by the movement of your breasts. This movement stretches the thin Cooper’s ligaments that surround the breasts, which is why it’s crucial you invest in a good sports bra that fits properly. And no matter how good it is, you should replace it when it shows signs of wear and tear. If it’s not supporting you properly, you may as well not be wearing it.
Choose carefully when buying a sports bra. Go to a running store, which will have high-impact sports bras for runners. Look for one with wicking fabric, so you stay cool, and make sure the seams won’t chafe. And remember, your sports-bra size may not be the same as your usual bra size.
