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 and theater costume designer Polly Smith with the help of Smith's assistant, Hinda Schreiber. Both Lindahl and her sister, Victoria Woodrow, complained about their bad experience exercising in ordinary bras, having experienced runaway straps, chafing and sore breasts. During the course of Lindahl and Smith's exploration for a better alternative, it was suggested that what they needed was a jockstrap for women's breasts.
