Young Sport Girl Wearing A Sports Bra

A sports bra is a bra that provides additional support to female breasts during physical exercise. Sturdier than typical bras, they minimize breast movement, alleviate discomfort, and reduce potential damage to chest ligaments. 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. Larger breasted women may be prevented from taking part in sports or exercise when their breasts move excessively.
Design and history
The first commercially available sports bra was the "Free Swing Tennis Bra" introduced by Glamorise Foundations, Inc. in 1975. The first general exercise bra, initially called a "jockbra", was invented in 1977 by Lisa Lindahl. Her sister, Victoria Woodrow, called to complain about her bad experience exercising in ordinary bras. She was frustrated by runaway bra straps, chafing skin, and sore breasts after running. Hinda Miller and Lisa Lindahl cut up a pair of jockstraps and sewed them together into a bra; and marketed the garment as the Jogbra.
