How To Find The Right Sports Bra for Optimal Comfort and Support

Fall is almost upon us. In anticipation of a welcome, refreshing chill in the air and lush outdoor scenery, there’s no time like the present to breathe new life into your workout regime. But before so much as picking up a jump rope or dusting off your sneakers for running season, it’s important – make the essential – that you’re armed with the right sport bra.

‘Sports bras are often an afterthought, and most women are wearing ill – fitting ones without knowing it’, says Laure Tempesta, a sport bra expert and founder of Bravolution. ‘During exercise, force on the breast is intensified and wearing the wrong size will cause pain and discomfort’. And it’s not just about short – term benefits – the effects of wearing the wrong sport bra, especially on the neck and back, are cumulative over time.

‘Not enough sport, and the continuous compression of muscles in the neck line the upper traps, levator scapulae, and pectoral muscles can cause chronic postural overload’, explains Emily Kibert, a chiropractor and founder of the Urban Wellness Clinic. ‘This will place excess strain on the structures of the neck leading to tension headaches; muscle tightness; short, shallow breathing; anxiety; and nerve pain’.

From finding just the right moment of stretch to the nuances of strap and underband size, here is a guide to picking the best sport bra for optimal comfort and health.

Be Wary Of Too Much Stretch

There’s a simple rule of thumb for overall fit: ‘The more a sports bra stretches, the more your breasts will move’, explains Tempesta. ‘Sport bras need to fit tighter than everyday bras, but not so tight that you feel restricted or like you can’t breathe’. While a style may seem more comfortable because it’s stretchy, the likelihood of breast pain goes up with the breast displacement. How much ‘give’ you can withstand is dependent on how high-impact your activity is. ‘For yoga, you can get away with more stretch’, Tempesta says. ‘But with running, any stretch in the straps, cups, or even underband will result in excessive breast movement. I cringe every time I see a woman running in a bra that was clearly made for yoga’. When weighing the options, it’s all about finding the right combination of encapsulation and compression – especially for larger bust, where the breast must be contained as well as compressed to reduce movement. That being said, you have to be careful a style doesn’t fit too small. ‘It will compress the muscles in the upper back, which are usually tight if you sit hunched over a computer all day’, says Kiberd, who adds that it will also prevent proper lymph drainage, which is the body’s natural system for ridding the body of toxins and inflammation.

‘Women often assume their bra size is set in stone’, says Tempesta. ‘But it’s a mistake to simply buy your usual bra size. Bras are like any other type of garment: You aren’t always going to be the same size in every manufacturer and every style’. For robust support, avoiding exposed breast tissue is ideal. ‘If you can see cleavage, the bra is either the wrong size or not a good fit for your shape’, she says. If you’re going to be using the bra in a high-intensity capacity, you should be testing it out accordingly in the dressing room by running in place, as well as jumping up and down. Better yet, use the slow-motion video feature on your smartphone to film yourself as you move and observe how your breast are moving in the bra. ‘You’ll be surprising how much breast tissue will spill out of an ill-fitting bra when viewed in slow motion’, says Tempesta.

‘Most of the bra’s support should come from the underbrand’, insist Tempesta. ‘If it’s too loose or not supportive enough, the burden of support will move to the shoulder straps and that will cause shoulder and back pain’. To ensure an underband is tight enough, Tempesta recommends reaching around and pulling the underband away from the back to gauge how much room there is. ‘Is shouldn’t pull out more than an inch for high-impact exercise’, she says. ‘You need enough room to expand your lungs, but you don’t want the band to shift, which will cause chafing. You want the underband to lock down and support you’.

One of the most common mistakes Tempest encounters are straps that aren’t the right length or veer towards too thin. ‘Generally, wider shoulder straps help distribute the pressure and weight better’, she explains. ‘Thin shoulder straps dig in and can cause pain’. When the latter happens, the compression from the tight straps causes constriction on the brachial plexus, ‘an important nerve bundle that goes from your neck into your arm’, warns Kibered. In terms of strap span, it’s important that a design doesn’t go too high up on the neck, which can cause shoulder and neck pain. In terms of design, as long as the straps aren’t too skinny, crossed-back styles tend to provide more stability and postural support as they ‘maintain a better position of the shoulders’, says Kiberd.

When it comes to performance fabrics, it’s a myth that cotton is better than synthetics for athletic use. ‘Cotton absorbs moisture, but doesn’t allow it to dry quickly’, says Tempesta. Another detail to consider is how much padding there is in the cups, as foam absorbs sweat and doesn’t dry quickly. ‘Excessive moisture in the breast area can lead to chafing and discomfort’, says Tempesta. Always opt for breathable materials like microfiber nylon or polyester to ‘let your skin and muscles breathe as you work up a sweat’, says Kiberd.
