No matter what sports girls do, they should wear sports bras. Because the chest is very fragile, any intensity of exercise may damage it, so it needs the close protection of sports bra. Wear a sports bra if you don't want your chest to contract and sag. Like I usually do yoga, but I also want to wear a sports bra, which can fix my chest from sports injuries and prevent sports injuries. Don't regret when you are old. You must wear a sports bra to do sports now!
