How to choose the best sports bra for you
There are lots of factors that will determine which sports bra you should go for. The main things to consider are the intensity of the exercise you’re doing, your breast size, and whether you want compression, encapsulation or both in the bra design.
Sports bras and intensity levels
- Level of support
The best sports bras for low intensity exercise like yoga, ballet or walking are light support bras. They use stretch fabrics to provide a little gentle compression which supports the breast, are highly breathable and very comfortable.
Meanwhile, medium support bras offer more structured support, with firmer fabrics and formed cups. This makes them ideal for low-impact cardio workouts such as cycling or a gym session.
At the other end of the scale, high-intensity activates such as running, crossfire and tennis call for high support bras - such as our top pick, the Shock Absorber Ultimate Run Bra. They provide a high level of support that keep your breasts secure and supported, which prevents damage to the breast tissue. This also makes them the best sports bras for large breasts.
- Compression, encapsulation or both
Another thing to consider is the type of support you want from your sports bra, and there are two options. The first is compression, where firm stretch fabrics and straps compress the breasts to the body which stops them moving independently or reduces that movement. The second is encapsulation, where each bra is supported or cradled its own cup, sometimes also with under-wiring. Light support bras usually use compression, medium support bras usually use encapsulation, and high support bras will use a combination of both.
- Sizing
It’s also really important you wear the right size sports bra for your boobs. Most online retailers will take you through a step-by-step guide on how to to measure yourself to get your chest and cup size. Many department stores and lingerie shops also have professional fitters who can do this for you.

1. Shock Absorber Ultimate Run Bra

Reasons to avoid
Ask a group of women what their preferred sports bra is, and most of them will say the Shock Absorber Ultimate Run Bra. Engineered to provide the perfect combination of encapsulation and compression, this bra will ensure that your ladies don't bounce around during high-impact exercise. This bra isn't just good for running; we've used it for everything from high-impact aerobics and cross-fit to mountain biking. A wide chest band combined with a high racer-back clasp to spread the load over a larger area of the back and shoulders means no pinch-points or chaffing, and the straps are easily adjustable so you can tailor their length to ensure the best possible fit. It's available in a great range of sizes, from 30A up to 38G, which means small and large busted women are both well catered to.
2. Lululemon Enlite Bra

Yes, the Lululemon Enlite Bra is expensive, but it's also amazing. It provides the coveted combination of high support plus flattering shape, comfort and breathability. Consisting of shaped cups, interwoven firm-but-stretchy straps that cross the upper back and an underband with clasp system that sits flat against the skin without chafing, the support level while running is impressive and it's great for other high intensity exercise too.
The construction means it's also relatively easy to take off when sweaty post-exercise, which can be a struggle with some bras. Seams that are bonded rather than stitched sit flush against the skin eliminating the risk of rubbing and making the bra streamlined and considerably less bulky and lower profile than other sports bras. If you're shopping from the UK, good luck figuring out the sizing system, though.
3. Marks and Spencer Extra High Impact Serious Sports Bra
Specifications

Almost as popular as the Shock Absorber bra, this Extra High Impact bra from good old M&S proves that you don't need to spend an absolute fortune to get a bra that will keep your boobs well supported. The wide underband provides excellent support with four hook-and-eye closures distributing pressure smoothly over a wide area so no pinching or rubbing. The shoulder straps are adjustable and sit in a traditional bra rather than racerback style, though some users have noted that the straps can slip down if not adjusted nice and tightly. The straps can also be adjusted at the back to a cross-over pattern if preferred.
4. Sweaty Betty Stamina Bra

Reasons to avoid
If you're looking for light-to-medium support with plenty of comfort and a stretch that allows you to move freely, then the Stamina Sports Bra from Sweaty Betty ticks all the boxes. Available in a range of colours designed to coordinate with other products in Sweaty Betty's product range, the bra is constructed from a seam-free knit fabric that means no chafing and plenty of breathability. The fabric offers light support to all sizes, and medium support up to a C-size cup thanks to a deep underband design. It's ideal for yoga, pilates or just lounging about the house when you might want some support but don't need to fully strap down the boobs.
5. Triumph Triaction Energy Lite
Specifications

Reasons to avoid
A popular bra among sporty women, the Triaction Energy Lite is a great choice if you're looking for medium support with a great shape. Like the Shock Absorber bra, its credentials have been independently verified by the University of Portsmouth (opens in new tab), and it will keep nicely supported for a range of high-energy activities such as cycling, dance or gym workouts.
Shaped cups provide a nice look and feel but without underwiring which can dig in when exercising. The wider underband combined with wide, padded straps provides plenty of security but women with larger busts may need a bit more support for high-intensity activities. It's nice and breathable so you'll keep cool even when you're working up a sweat.
