We’re Fitness Editors Who’ve Spent Nine Years Testing for the Perfect Sports Bra—These 15 Get Our Vote

Making sure you're wearing one of the best sports bras is important. Why? Well, because as a study from 2023 highlighted, your breasts can move with as much force as an F1 car when running - in other words, a lot.

Your body deserves the right amount of support, which is where our edit of the best sports bras comes in. Why should you trust us? Well, I'm Ally Head, the Senior Health Editor here at Marie Claire UK, meaning I test workout kit day in, day out, and have been for the best part of nine years now. I get front-row seats at press trips explaining the latest advancements in technology when it comes to workout gear, and I run marathons for fun, too, meaning I know from personal, sweaty experience what a good bra needs. I've also listed the go-to bras of a few fellow fitness editors, too.

So, why is investing in the right sports bra so key? Can't you just wear your buttery soft yoga bra? Short answer: not if you want to get a good workout in. Wearing the wrong bra will not only impact how you move (there's nothing worse than being asked to do high knees or burpees when you're wearing a bra designed for low impact), but also runs the risk of damaging your boobs. That's because breast tissue is largely supported by your skin and ligaments, meaning you need a little extra hand to avoid breast pain and issues further down the line.

So without further ado, scroll my edit of the bras genuinely worth your money and investment. I've made clear what support they offer, what workouts they're best for, and the main pros and cons I noted when testing, too. On the hunt for other workout clothes, too?

Testing process for the best sports bras

MC UK Senior Health Editor and nine-time marathoner Ally Head, triathlete and fitness writer Alice Barraclough, personal trainer and fitness writer Chloe Gray, dance teacher Chloe Woods, MC UK Junior Shopping Editor Amelia Yeomans, MC UK Fashion Writer and runner Sofia Piza and MC UK Senior Beauty Editor Katie Thomas have all tested the bras in this round-up personally.

Keen to know more about how team MC test products? Each item of gym wear has been tested during at least three workouts. That might look like sweat-testing it on a run, a walk, and a gym workout. Rest assured, though, they've all been personally tested by my team and me, so you know your money is being spent on a product we genuinely own ourselves and recommend.

What did we look for when deciding on the best sports bras?

• Support: Is the bra supportive enough and does it hold your breasts in place?
• Straps: Are the straps adjustable and comfortable?
• Material: Is the material breathable, high-performance and sweat-wicking? Does the fabric chafe?
• Fit: Are there a wide range of fits, sizes and options available for all breast sizes and shapes?

We've indicated next to each of our best sports bras what support they offer and what workout they'd be best for - because there's nothing more infuriating than a bra that doesn't support you through your sweat sessions, rubs, or rolls down every two seconds.

Best sports bras of 2026, tried and tested by team MC

Best sports bras for running

Tested by: Ally Head, marathon runner and MC UK Senior Health Editor, and Chloe Woods, dance teacher.

What we thought when testing: "I wore this bra for my first Boston Qualifying Marathon - the London Marathon in 2021 - which speaks volumes about how much I rate it. It's easy to put on, butter-soft, and seriously supportive, too, holding your boobs in place without leaving you feeling constricted. As with all lulu kit, it sweat wicks well and dries quickly, too, meaning you're not left feeling uncomfortable or chafed after your session," shares Head.

"This is my go-to sports bra, especially for running. The straps keep you secure, not to mention they're flattering, too," adds Woods.

Tested by: Ally Head, marathon runner and MC UK Senior Health Editor.

What we thought when testing: "Coming in a range of sizes from C to H, this is a bit of a game changer when it comes to high-impact bras that actually hold you in. It promises zero bounce and delivers on it, not to mention is easy to take off, thanks to its fully opening back."

"This bra is great for runners who cover lots of mileage or anyone who wants to invest in a bra that will last the long run. It's got a high neck for extra coverage and offers maximum support, so you can wear it for any workout and not have to worry about your boobs moving."

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing: "When I tested over a ten-mile long run and two shorter runs, I was impressed with ON's first running bra. It's comfortable, breathable, and offers just the right amount of support. I also rated the fact that the straps didn't move, staying in place thanks to the responsive elastic which moves with your body."

Tested by: Amelia Yeomans, MC UK Junior Shopping Editor.

What we thought when testing: "I will rave about this Gymshark bra to anyone that will listen. I bought it on a whim whilst it was on sale and it's one of the best investments I could've made. I've worn it for running, Pilates, hiking, boxing, and everything in between, and it's never let me down. Despite being advertised as medium support, I find it provides ample hold for my larger chest - even when running - but it's comfortable enough for low-impact workouts too without any oppressive compression.

The ruched design gives it a stylish feel that means it could easily be worn as your top, and there are plenty of chic colours to choose from. The fabric is buttery soft and sweat wicks very well, which is essential for me as I sweat a lot in that area when working out. It definitely fits true to size, but you can always size down if you want even more support as the fabric is stretchy enough to allow some wiggle room."

Best sports bra for low impact workouts

Tested by: Ally Head, marathon runner and MC UK Senior Health Editor.

What we thought when testing: I've been curious about Vuori kit for a while, reported to be a firm celeb favourite and seen on the likes Harry Styles and Kylie Jenner. While their kit isn't supportive enough to see you through marathons, it is super soft, comfortable to wear for low to medium impact sessions, and also cute for brunch, too. Invest in their Daily design - one of their highest support offerings - if you want a sports bra that's comfortable, soft, yet sweat wicks, too.

Best supportive sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing: "Fun fact: Maaree bras are the only in the world that have an overband, aka a curved panel that runs over the top of the boobs to reduce upward motion. Designed with high impact in mind, check out their bras if you're after extra hold."

"There are a lot of bad sports bras out there but this certainly isn't one of them. I've run-tested over short and long distances and it really does offer the right support. I like that slightly longer line support under the bust - it offered me extra comfort and extra confidence, too."

Best sports bra for HIIT workouts

Tested by: Sofia Piza, half marathon runner and MC UK Fashion Writer.

What we thought when testing: "The Battle Bra was created to support the figure of eight motion naturally created by your breasts while working out and comes in 35 different sizes. This sports bra has quickly become a new go-to in my kit rotation. I found the fit true to size with no uncomfortable gapping or tightness on the skin. The material is buttery soft and moisture-wicking, too. I've used this bra both for running and high-intensity workouts and almost forgot I was wearing it every time I tested - a huge bonus when working out," shares Piza.

Best sports bra for large breasts

Tested by: Jadie Troy-Pryde, MC UK News Editor.

What we thought when testing: "Testing gym bras for a bigger bust has become a sport in itself for me, and I can attest to the fact that not every promise of high-impact support can be sustained. However, I’m obsessed with the Lululemon Go Further Bra. It’s completely seamless, which means it perfectly contours to your bust and back, and omits a stacked hook and eye clasp (a regular feature in DD+ bras) in favour of seemingly super-strength racerback straps. I've been testing it for runs, weight sessions and reformer pilates classes, and it’s incredibly lightweight considering the level of support it offers. Plus, it delivers on compression without compromising on comfort. At £88, it’s definitely on the pricier side, but as anyone with a fuller cup will tell you: when you *finally* find an excellent sports bra, your loyalty to it knows no bounds, and you will hold on to it for as long as the fabric allows."

Tested by: Katie Thomas, MC UK Senior Beauty Editor.

What we thought when testing: "Before I had my son, my breasts were a perky DD. Now they're a G and I've had to completely rethink my brands when it comes to keeping the girls in place. PeBe wants to make sure you're wearing the right size, so if you don't quite nail it the first time, they'll arrange an online consultation to get the fit just right. I have to be honest, it is a little tricky to put on, but there are handy instructional videos on their Instagram that helped a lot the first time."

Best sustainable sports bra

Tested by: Chloe Gray, health writer and personal trainer.

What we thought when testing: "I don't go out on a run without this Adidas bra on," shares Gray. "It's one of the only items I've worn where I don't feel my boobs bouncing thanks to the higher neck design and the material is so soft it doesn't dig in or rub. The details look good but are actually all about function: a clasp fastening and adjustable cross straps mean everything is snug and perfectly tailored to your body."

This item, being part of a limited collection, is now sold out. However, Adidas have a range of other high support sports bras for you to browse.

Best all-rounder sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing: "This has fast become one of my go-to sports bras, as you can see from the hero image where I'm wearing it. It's hard to fault it, but I wear it on repeat because it ticks all of the right boxes: it holds your boobs in place without being uncomfortable, is breathable without letting you get cold, and offers adequate support without cutting you in half - not to mention, it looks good, while doing it."

"Do note: the straps aren't adjustable, though."

Best long-line sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing? "Like the sound of a lightweight, comfortable, fashion-forward sports bra? Enter stage right, the Adanola tank, which offers long-line support, spaghetti straps, and a rounded high neckline. I love that this sports bra has more of a longline fit, great for those wanting a bit of extra coverage across their ribcage. It also has a compressive fit and sculpting finish, sweat-wicking well during your session and allowing you to remove the padding, if you'd prefer. That said, it's definitely not supportive enough for high intensity exercise - keep in your drawer for yoga, strength training, Pilates, and so on."

Best compressive sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing? "If you're after a seriously high support bra with a compressive fit, look no further. This Represent design has a second-skin feel for ultimate comfort, as well as sweat-wicking material with antibacterial properties. It has an adjustable bra-like hooked back for the perfect fit, and it features reflective details for added safety when running. Going up to a size XXL, this is a bra that will keep your chest held in without discomfort or sweating."

Best thin strap sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing? "Sports bras typically have thick straps that are visible under vests or tank tops, so I love this spaghetti strap design that's ideal for layering with a more minimalist look. Like all Oner pieces, this bra is soft and sweat-wicking to keep you comfortable through a low-impact workout - and it has removable bra pads so you can adjust it to your liking. The crossover straps offer a good amount of hold for gym floor workouts or Pilates, and I love this muted yellow colourway too."

Most stylish sports bra

Tested by: Ally Head, marathon runner and MC UK Health Editor.

What we thought when testing? "We're huge fans of Monday Body at MC, and this new bra is no exception. I fell in love with the piping that makes it feel instantly stylish and elevated, but the super soft material and adjustable straps make for a comfortable low impact workout too. It's become my go-to for Pilates and hikes where I need a bra that will wick sweat and not dig in, but also looks good enough to wear on its own as a top. This ticks every box."
