A sports bra fitted to your size and with the right support level will minimize the impact of your chest’s movement during exercise, allowing you to exercise pain-free. If you require a high level of support for your bust size or activity type, it’s important to look for medium- or high-support bras with compression that will hold your breasts to your chest wall. Also, search for encapsulation support, which usually comes from separate internal cups that hold and support your breasts individually. This will prevent pain or strain while exercising. Adjustability and ClosuresYou can also machine-wash most bras unless the manufacturer states otherwise. “If you put your bras in the washing machine, use a lingerie mesh bag and always hook the bra before putting it in. Place it in a delicate cycle and only place lightweight delicates in the wash with them. Never put your bras in the dryer—the heat melts the delicate fibers and elastic,” she adds. While it’s tempting to simply toss a sweaty bra into the washing machine after a killer workout, “I always recommend that you hand wash your bras in a mild detergent for lingerie. A three-to-five-minute soak in the sink should do,” Laporte recommends. Nolte, K., Burgoyne, S., Nolte, H., Van Der Meulen, J., & Fletcher, L. (2016).

Low-impact sports bras have light compression and a more minimal support structure for light activities like stretching, walking, yoga, and barre. They usually have thinner straps and bands, which sometimes make them less ideal for larger breasts. Medium-impact sports bras have more compression, internal structure, and wider straps. They’re a good choice for activities like cycling, barre, studio fitness classes, and shorter, less-intense runs. The best way to prevent BPA exposure is to make educated decisions in choosing your personal care products,” explains Joshua Zeichner, MD, associate professor of dermatology and director of cosmetic and clinical research in dermatology at Mount Sinai Hospital. As a precaution, it is best to limit the amount of time you spend in activewear by changing out of it when you are finished working out.

Choose a bra with support features that will make it comfortable for the workout you’re doing. “High-impact bras are great for running, jumping, weight training, etc., whereas low-impact sports bras are good for activities such as yoga, and Pilates,” Amanda Barton says. She adds that the support level you need usually corresponds to your activity intensity. It’s no secret that wearing a sports bra when you work out is of utmost importance. But have you got your perfect fit? Made for high-impact moves, the molded cups separate and support to keep bounce at bay (which can be especially helpful for larger busts). Best of all, the band, straps, and edges are soft and body-smoothing, yet don’t dig in. Bowles K-A, Steele JR. Effects of strap cushions and strap orientation on comfort and sports bra performance. Medicine & Science in Sports & Exercise. 2013;45(6):1113-1119. doi:10.1249/mss.0b013e3182808a21 The band should fit snug, and the cups of the bra should lay smooth, with all breast tissue contained inside,” Heather Laporte says. “Straps should hold very minimal weight. Choose a bra that has adjustable straps for comfort and support.”All three support levels have specially designed materials and structures appropriate to their intended use. “High-impact sports bras are designed to meet the extra demands of any active lifestyle,” Laporte says. “They have stronger, more supportive materials than low-impact sports bras and have a different construction overall that makes them more supportive to guarantee less up and down movement of the breast.”

Adjustable straps and bands provide a customizable fit, which can be beneficial for larger breasts or varying workout intensities. A bra with adjustable straps should be carefully chosen and fitted, says Laporte. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ The impact level describes the type of activity that the bra would be suited for,'' Ferriter says. “High-impact bras will be for your higher impact movement, like running, jumping, HIIT training, and plyometric work. Lower-impact will be best for activities like walking, jogging, strength training, and even walking around town.” Medium impact is between support levels and is great for activities like cycling, barre, and studio fitness classes.

Medicine & Science in Sports & Exercise, 45(6), 1113–1119. doi:10.1249/MSS.0b013e3182808a21 High-impact sports bras provide the best level of bounce control. They have high compression, advanced structure, and wide, usually adjustable straps or bands. Wear these for high-impact activities that involve intense multi-planar movements, like jumping and bending at a fast pace and running. In May 2023, the Center for Environmental Health (CEH) announced that, after testing, it found high levels of BPA in certain activewear pieces containing blends of polyester and spandex, including sports bras from Sweaty Betty, leggings from Nike, Athleta, Champion, Patagonia, and Kohl’s, shorts from Champion, Nike, and Adidas, and athletic shirts from Fabletics. We may recommend some of these products or similar items from these brands in this list, as these products have not been recalled and the science on transdermal absorption of BPA is still not settled.

Bisphenol A (BPA) is a chemical found in some types of plastic. Research has shown that exposure to high levels of BPA can lead to obesity, hormonal imbalances, and uterine cancer, among other health complications.
