Gymshark Sports Bras: Sizing And Fits

It's no secret that wearing a sports bra is 'hella important. Wearing the right sports bra size whilst you train minimises the impact of your chest's movement during exercise, allowing for an easy, pain-free workout. Trust us, even if you're a long-serving member of the itty bitty committee, don't be fooled into thinking you can do without.

First things first: sports bra sizing. Your sports bra should fit comfortably snug, but not so tight that it feels suffocating to wear. Okay, so it may feel like a mission to put on in the changing room but, keeping your chest secure and reducing bounce helps to alleviate both back and breast pain.

A good sports bra can also help your girls stay perky... we know, why weren't we taught this at school?! Physical exercise, be it box jumps or running for your Uber at three in the morning, (weighty chips and garlic mayo in hand ofc), puts your Coopers Ligaments - the thin connective tissue that supports your boobs structure - under huge strain. Without the right support, you could be causing irreversible damage to your girls and their perkiness. It's better you found out now, right?

In short, you'll want to find a style that's best for your particular size, breast shape and activity level... and you thought finding a normal bra was hard enough. Depending on the impact of the activity (low, medium or high), there are different sports bras, and support levels to suit. From the padded sports bra straight through to the strappy sports bra - supporting 'yo girls during a workout has never been easier.

Like most things though, not every sports bra is going to be the same; its fit, its design, its purpose - everything will differ ever so slightly, so don't be concerned if your sports bra size isn't a direct comparison of your usual t-shirt bra size!

In the ultimate Gymshark Sports Bra Size Guide We'll Be Answering The Following:

  • How do you measure for the best sports bra size?

  • What size Gymshark sports bra should I get?

  • What are the differences between a low, medium and high support sports bra?

  • Which style/type of sports bra is right for me?

Sports Bra Sizing: How To Measure For The Best Sports Bra Size And Fit

There are 2 simple measurements to follow prior to buying your sports bra...

Yes... 80-100% of women really are wearing the wrong size bra. And we all know us ladies are very rarely wrong, so it's time we sort this out once and for all.

To ensure that your sports bra fits like a dream, we're talking: no chafe, no shoulder pain, no uniboob bulge; we've put together two simple steps for you to follow.

How To Measure For Your Sports Bra Size:

  • Step 1: Measure your bust:

    Wrap the measuring tape around the fullest part of your bust - nipple to nipple. Ensure that you don't pull the tape too tight; it should be snug, but still loose enough for you to fit a finger between the tape and your body.

  • Step 2: Measure your under bust:

    Place the tape measure firmly around your chest, letting it rest just under your bust. Ensure that the tape lies flat against your back, again the tape should be snug, but still loose enough for you to fit a finger between the tape and your body.

Now that you have your two main measurements, it's time to find your sports bra size so that you can get the best cup for your coin...

Which Gymshark Sports Bra Size Should I Get?

Introducing: The Gymshark Sports Bra Size Guide.

As mentioned earlier, your sports bra sizing is reliant on two measurements: your bust and your under bust. Take a look above if you're unsure on how to take these measurements.

Once you're happy with the readings on your tape measure, reference them to the chart below to find your perfect sports bra size at Gymshark.

The "Does My Sports Bra Size Fit Me?" Test

Now that you've found your ideal sports bra size and it's sat there in all it's bright, newbie glory, try the sports bra on and test its fit.

When trialling any sports bra size, you'll want to focus on three aspects: the straps, the under band and the fit of the cup. If one of these components is just slightly off, let's face it, you've not got the best cup for your coin; with minimised support, you're back to the drawing board. Don't be disheartened though, it can take a while to find the perfect counterpart.

When testing a sports bra size, trial the following features out to ensure the best fit:

  • Straps: as a rule of thumb, you should always be able to place a finger underneath the straps of your sports bra. If you're not able to, we'd recommend loosening your straps ever so slightly (if applicable). Ensure that you don't go from one extreme to another though, loose straps reduce the support offered.

  • Under Band: lift your arms above your head - if your sports bra rides up and doesn't sit flat to your chest, it's likely to be a little too big which could result in chafing during your workout. Try adjusting the straps slightly. If it continues to move, we'd suggest going down a size.

  • Cup: if you're testing a padded sports bra, your girls should be comfortably sat within the cups. No matter how weird it may look, scoop them on in and do a little jiggle around. If the cup is too small, or not the right style for your breast shape, you'll notice that your boob pokes/bulges out slightly - here we'd recommend either sizing up or trying an alternative sports bra design.

So, the question is: does your sports bra really fit you? Like really really fit you, and does it fit you well?

Can you lift, jump, downward dog and more in your sports bra without the fear of your girls falling out?

If you've answered no to the above, we promise you - despite what you may think - the world is not over. Yes, there is still hope - it might just be that you need to alter your sports bra size slightly or, opt for an alternative style/design of sports bra that suits your build that little bit better.

If you're still unsure on which sports bra size you should go for, please just give us a message below! We'll happily help you out best we can with your sports bra sizing! 


To keep your sports bra in the best condition possible, please remove all padding (if removable) prior to washing. Those sports bra pads just need a gentle hand wash so as to avoid ruining their shape and structure!

Let's Summarise All Of That Copy Into Picture Form

. . .

Which style of sports bra is right for me?

It's one of the hardest questions within the boob-sphere. You know how your sports bra should fit, you understand the importance of its support and by now, you're happy to call yourself a veteran of the all-important "bounce test"... but those are just the basics.

The STYLE of your sports bra is just as important as its fit. With a steady increase in women ditching the workout t-shirt altogether, believe us when we say that the search for a sports bra resembling something other than a "breast bag" from the 1970s is high. And yes, that really was a thing.

Although we want you looking great at the gym, we ask that you don't focus solely on the aesthetics of the sports bra, but more towards its function, design detailing and fit - take a read of the specs and learn the benefits of the design. For example: wide, adjustable sports bra straps = increased support.

Which sports bra is right for you falls down to the size and shape of your breasts and the type of activity you partake in.

Below, we've outlined the difference between our current styles of sports bras: low support, medium support and high support; which sports you'd typically wear each for, and the sizes that they're available in (ps - all sports bras will be available in sizes XS-XL, can we get a hell yeah!).

. . .

Following some bio-mechanical testing, and a whole lot of research, we have created a brand new range of sports bras. Each have been carefully designed to keep you feeling comfortable and supported through any workout.

. . .

Low Support Sports Bras:

What is a Low Support Sports Bra?

Low support sports bras are designed to be worn for activities that don't incur a large amount of bounce. Whilst this may mean that their design revolves around inimitable comfort, it does tend to mean that minimal support is offered to your girls.

Low Support Sports Bras: 

What Sports Do I Typically Wear Low Support Sports Bras For?

  • Walking

  • Stretching

  • Heavy Lifting

. . .

Medium Support Sports Bras:

What is a Medium Support Sports Bra?

Medium support sports bras are designed to be worn for activities that are slightly more intense than yoga/pilates (otherwise known as low impact activities). In short, if a sports bra isn't worn during a medium impact workout, your girls would be bouncing up, down and all around.

Their design focuses on supportive detailing, with many offering an "encapsulation" design (defined cup structure to encapsulate each breast, providing you with a medium-level of support, and a feminine build. No uniboobs).

Medium Support Sports Bras: 

What Sports Do I Typically Wear Medium Support, And Medium-High Support Sports Bras For?

  • Spinning

  • Combat

  • Functional Fitness

. . .

High Support Sports Bras:

What is a High Support Sports Bra?

High support sports bras are designed to be worn for activities that incur a large amount of bounce, or movement. (You know those activities that if you were wearing a normal t-shirt bra, you'd be holding your breasts... take for example, running for the bus, or up the stairs etc).

Designed limit bounce as much as possible, its design focuses on both the straps and fastening - straps tend to be thicker and wider; the underband thicker, with a bra-like fastening for additional support. In addition to this, you'll notice that high support sports bras offer more of a compression/encapsulation fit - with padding becoming a non-removable option.

High Support Sports Bras: 

What Sports Do I Typically Wear High Support Sports Bras For?

  • Running

  • HIIT

  • Functional Fitness
