These are *officially* the 18 best items of gym wear you can buy, according to six fitness pros
Kit that flatters, sweat wicks and lasts the long run.
Knowing what constitutes the best gym wear - in other words, the fit kit that will genuinely stand the test of time and support you through even the sweatiest of workouts - can sometimes feel like a chore. Will the sweat-wicking leggings genuinely sweat wick? And will that extra supportive bra genuinely be extra supportive or just another gimmick?
To help you cut through the noise, we've asked four fitness experts who test workout gear for a living and tried literally thousands of designs in their time for their desert island kit picks. In other words, we picked their brains about their ride-or-die gym wear items that they use day in, day out, and couldn't live without.
The below are the best of the best, never rolling down, stretching after a few washes, showing sweat patches or providing inadequate support. We're not about buying for the sake of it here at Marie Claire UK, rather, investing in items that'll last the long run. Know this, though: one study carried out by Barbell Apparel in 2021 found that of 2000 regular gym-goers, 79% of people believe that owning good gym wear is a key step in achieving your fitness goals.
So yep - having supportive, sweat-wicking workout clothing is important. Luckily the gym wear game has never been stronger, with designers, high street brands and sports labels answering our need for functional and fashionable workout kit.

Best gym wear: 18 bits of fit kit to buy now
All of the products in this roundup have been tried and tested by team Marie Claire UK.
We enlisted the help of MC UK Senior Health Editor, Ally Head, an avid marathon runner who loves strength training, Junior Shopping Editor Valeza Bakolli, who might skip the running malarkey but loves an at-home Barre or yoga workout, fitness writer and triathlon-loving Alice Barraclough, personal trainer and strength training-fan Chloe Gray, and personal trainer and head coach at PASSA Lillie Bleasdale, who's current marathon personal best sits at an impressive 3:03, not forgetting Pilates and sound bath-loving health writer Dionne Brighton and HIIT- loving Editor Grace Lindsay.
Keep scrolling for their top recommendations.
The best workout leggings
If you've read our guide to the best gym leggings, then you'll know that there are quite literally thousands of options to choose from. It was hard to narrow it down, but all four fitness pros agreed that the below two pairs were their absolute favourites.
lululemon Wunder Train High-Rise Tight 25"
Reasons to buy
Reasons to avoid
What we thought when testing? lululemon leggings have a cult-like following for a reason - because, simply put, they're the best. They're an investment, but they are easily the comfiest leggings we've tried and they really do last forever.
While there are lots of styles to choose from, MC UK Senior Health Editor Ally Head is a big fan of the "Wunder Train" style in black. Designed with sweat and support in mind, they're butter soft, sweat-wick well, and never cut you in half, either (she's run several half marathons in them, so you know you're in good hands).
Bleasdale agrees, adding that they're one of her go-to's for strength training, long runs, and recovery yoga. NB, here: the 25" leg length will be great for petite women under the height of 5 foot 2 but do opt for a longer leg length if you're taller and don't want a cropped fit.
Adanola Ultimate Leggings
Reasons to buy
Reasons to avoid
What we thought when testing? For those of you looking for leggings that can be worn to your Saturday morning Pilates class and then to brunch afterwards, this Adanola pair might be more your style. Brighton is a huge fan of the brand, and these leggings are her go-to for more low-intensity workouts. They're incredibly flattering and come in various colours and leg lengths, like the lululemon tights.
The only downside is that they're not as sweat-wicking as other competitors (read: lighter colours will show sweat patches) and can pile and bobble more easily.
Nike One leggings
Reasons to buy
Reasons to avoid
What we thought when testing? There's a reason Nike is globally renowned for its fit kit - it's one of the best brands on the market and won't break the bank, either. Head's go-to workout legging from the brand is their One Luxe legging, worn by athletes and celebrities alike.
While they feel slightly thin when you first put them on, they insulate and sweat-wick well, keeping you warm, cool and supported throughout your session.
The best sports bras
If you're looking for one of the best sports bras, it's important to consider what kind of support you're looking for.
If you've got slighter bigger boobs and plan on doing a more intense workout, you might want to opt for something more supportive, like one of the best sports bras for big boobs. However, if you're doing something more gentle such as a yoga or Pilates class, then a low support bra should do the trick.
We've included our top picks for each, so you're fully covered, no matter the workout intensity.
Under Armour Infinity Mid Covered Sports Bra
Reasons to buy
Reasons to avoid
What we thought when testing? For medium support, you can't go wrong with this bra from Under Armour. The design boasts a soft, breathable structure, the material is super sweat-wicking and it even contains mesh panels for added airflow. It runs true to size and comes with adjustable straps to fit you perfectly.
ON Running Performance Bra
Reasons to buy
Reasons to avoid
What we thought when testing? Need a more supportive bra? Look no further than ON Running. The brand's Performance Bra is comfortable, breathable, and offers just the right amount of support. It's great if you're a runner who trains over long distances as the straps contain responsive elastic to move with your body and ensure the bra supports you in the right ways. Plus, it's breathable thanks to the full mesh racerback panel on the back. Win, win.
Sweaty Betty Zero Gravity Running Bra
Reasons to buy
Reasons to avoid
What we thought when testing? The Sweaty Betty Zero Gravity bra is one of Barraclough's top picks for its unrivalled support.
"There's been quite a lot of hype around Sweaty Betty's latest bra – the Zero Gravity Running Bra – and rightly so," she shares. "After over two years in development and numerous rounds of wear trials and bounce testing, it's finally hit the shops and we're impressed. Designed for running and high-impact exercise, this sports bra supports (not squashes) and is available in sizes 30A-38F."
Featuring thick almost neoprene-like seamless straps, an easy hook and eye closure and a quick-release top clasp so it's easy to get in and out of, this could well be our new favourite bra for chafe-free running. Plus, the colours are gorgeous, too.
lululemon High Support Energy Bra
Reasons to buy
Reasons to avoid
What we thought when testing? Head wore this bra for her first Boston Qualifying Marathon, the London Marathon in 2021. She chose it for race day for a number of reasons - it's high support, easy to put on, butter-soft, and has never chafed (and she's tested it on a lot of long runs). As with all lululemon kit, it sweat-wicks well and dries quickly, too, meaning you're not left feeling uncomfortable.
The best workout tops
Invested in a sports bra and now you're on the lookout for a top to wear with it? Luckily for you, here at Marie Claire UK, we're big fans of oversized gym t shirts, because let's face it, we don't always feel comfortable working out in just a crop top.
It's important to note here that the second t shirt below is made from cotton, and so is best worn for lower intensity workouts like Pilates or weight lifting (it won't sweat wick as well as the first).
Check out our top picks below.
Gymshark Vital Seamless T-shirt
Reasons to buy
Reasons to avoid
Gymshark is one of the best affordable gym wear brands out there and the t-shirts are no exception. If you're thinking about doing a more intense workout, opt for the Vital T-shirt. This design is breathable, sweat-wicking, and made from a super soft, stretchy material that won't irritate you during your workout.
lululemon Align Tank Top
Reasons to buy
Reasons to avoid
What we thought when testing? Another of Barraclough's top picks was this lululemon top, which, in her own words, she's "low-key obsessed with."
"With a built-in bra, you don't need to wear a sports bra underneath it (small caveat here: this top is probably only supportive enough for those with smaller chests)," she explains. "I love the low scoop-back design and wearing it for yoga, Pilates and even strength classes."
Other need-to-knows: it's tight-fitting and ever-so-slightly cropped to just above the waist, meaning it's super flattering and pairs perfectly with high-waisted leggings. Oh, and it's made from lululemon's Nulu fabric, which means, just like the famous Align leggings, it feels buttery-soft.
PE Nation Pioneer Tee
Reasons to buy
Reasons to avoid
What we thought when testing? When it comes to stylish, on-trend gym wear, no one does it better than PE Nation. This top is designed for lighter sweat sessions, and can also be styled with jeans and trainers for a casual daytime look.
Made from organic cotton and boasting sweat-wicking abilities, our one tip is to make sure to size down as we found it ran a little big.
The best workout shorts
Workout shorts are a great alternative to leggings in summer, but some roll down, some roll up, and well, some aren't supportive at all.
We've rounded up the best running shorts and the best cycling shorts so you can choose a pair depending on what workouts you tend to do. It goes without saying that running shorts are best for running, whereas cycling shorts can be worn for all sorts of sweat sessions such as running, cycling, gym sessions and more.
LNDR Peachy Keen Shorts
Reasons to buy
Reasons to avoid
What we thought when testing? Brighton loves these gym shorts because they're super supportive and great for taller girls, too. "I'm 5'6 so find it so difficult to find a pair of cycling shorts which are long enough and not too revealing. While the 5-inch was a bit too short for me, the 8-inch was a perfect fit and length to squat in the gym and feel comfortable."
Other pros: They're sweat-wicking and squat-proof, too.
Nike One Women's Dri-FIT High-Waisted 2-in-1 Shorts
Reasons to buy
Reasons to avoid
What we thought when testing? If a classic running short is what you're after, say hello to this pair from Nike. Head, MC UK's Senior Health Editor, tested them on a 20-mile run and found them both supportive and flattering. They come with a tight base layer and a loose outer layer, giving you lots of flexibility, not to mention come with sweat-wicking technology to keep you cool. All that for just under £40... bargain.
Sweaty Betty Power 6" Cycling Shorts
Reasons to buy
Reasons to avoid
What we thought when testing? Another of our favourite cycling shorts are the Power Shorts by Sweaty Betty. Much like the brand's Power Leggings, these shorts are supportive, sweat-wicking and look great on (if we do say so ourselves). We've worn them for various gym sessions and they have never chafed or moved around, which is a huge plus. If you don't like taking a bag to the gym, they also come with lots of pockets to store your belongings.
They're one of Bleasdale's top picks for the same reasons - "they're one of my all-time favourites as they offer the right amount of compression and support. I wear them on repeat."
New Balance London Acceptance Impact Run Fitted Short
Reasons to buy
Reasons to avoid
What we thought when testing: If you're a runner who needs pocket options for your mid or long runs, these shorts are for you. A firm favourite of both Head and Bleasdale, these cycling-style shorts sweat-wick well, dry quickly, and are more affordable than other similar options on the market.
The best matching gym sets
Never underestimate the power of a matching gym set. When we wear one of these, we feel like we totally have our life together, when in reality we've got five piles of laundry to do and 1000 emails to get back to. For that little bit of escapism, check out our favourites below.
MP Women's Adapt Reversible Sports Bra
Reasons to buy
Reasons to avoid
What we thought when testing? Writer Lindsay raves about this MyProtein set. Not only is it affordable, but the bright colours keep you motivated and the sports bra is reversible, so you get two looks in one. It's not the most supportive due to the halterneck fit, but it's great for a low impact workout class or a daily walk.
MP Women's Adapt Leggings
Reasons to buy
Reasons to avoid
What we thought when testing? The leggings are just as impressive, and Lindsay was surprised by how soft and comfortable they were when trying them out. They offer just the right amount of support (no one likes baggy leggings) without feeling too restrictive.
She found that they didn't roll down, crinkle at the knees or dig in at the waistband, so they get a five-star review from us.
adidas x Stella McCartney TruePace Bra
Reasons to buy
Reasons to avoid
What we thought when testing? This is Gray's go-to running bra, which she rates for its high support and neckline. While she's a fan of how it looks aesthetically and feels (hello, butter-soft material), she also likes that its main motive is performance, with a clasp fastening and adjustable cross straps which mean you're properly supported.
adidas Primeblue Designed To Move 2-in-1 Sport Shorts
Reasons to buy
Reasons to avoid
What we thought when testing? Last but by no means least, these adidas running shorts have a cult-like following for a reason. They're soft, breathable, and supportive, too - Head liked the underlayer which means no chafing or moving around over here.

What clothing is best for the gym?
One of the most important things to look for when it comes to gym clothes is sweat-wicking material that'll keep you cool, not to mention a supportive style. Depending on the workout, Senior Health Editor Ally Head is a fan of a supportive sports bra, butter-soft yet compressing leggings or shorts, and a cropped tee or later.
