A sports bra is a bra that provides support to a woman's breasts during physical exercise. Sturdier than typical bras, they minimize breast movement and alleviate discomfort. Many women wear sports bras to reduce pain and physical discomfort caused by breast movement during exercise. Some sports bras are designed to be worn as outerwear during exercise such as jogging. There are also sports bras with extra padding for exercises that involve some kind of trauma to the breasts.
