A sports bra is a bra that provides extra support for the breasts while the woman is exercising. Unlike a general bra, this bra reduces the amplitude of the chest's swing during exercise, thereby reducing discomfort and the risk of chest ligament strain. There are some sports bras designed to be worn outside (such as when jogging)
Today's most common sports bras are similar to a vest that has been cut in half, made of fibers that have high ductility and good sweat absorption (such as spandex), as well as products designed with gels, water pads and airbags.
After some surgery, some women also choose to wear a seamless sports bra to fix the chest to facilitate wound healing. ,
The shoulder strap of a common bra causes some women to exercise their arms, because the fixed bra is stretched and directly presses the trapezius muscle and feels nervous, which may eventually lead to numbness or pain in the shoulder. The sports bra can avoid this problem because it is tied to the back.
