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.” It’s no secret that wearing a sports bra when you work out is of utmost importance. But have you got your perfect fit? 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. Bowles K-A, Steele JR.

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. You 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. 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. 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.

Not only do they flatter many different body shapes, but they also provide ample support for your boobs during exercise. The higher coverage style of the bra means less chest movement, keeping everything in place and making your high-impact activities feel a lot more supported. We love that this high-coverage option is available in sizes that are based on both your band and cups for the perfect fit. Choose from three neutral colors.

Trust us, even if you're a long-serving member of the itty-bitty committee, don't be fooled into thinking your sports bra size doesn’t matter.

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.” 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.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. 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. She adds that you should ensure the bra offers full cup coverage and separation without any gaping or pinching. Before shopping, try using a tailor’s measuring tape or a bra fitting professional like Laporte to help you find your band and bust size. Then follow product measuring charts, professional recommendations, and your comfort level for the best success.
