What Should Plus-Size Men Wear to the Gym? A Guide to Fit, Comfort & Style
Going to the gym should be about your workout, not constantly thinking about whether your clothes fit right.
Finding gymwear that feels comfortable, moves with you and looks good can be surprisingly difficult when you're shopping for extended sizes. A T-shirt may fit across the chest but feel restrictive elsewhere. Track pants might have the right waist but feel uncomfortable around the thighs. Or a piece may technically be available in your size but simply not be designed with your proportions in mind.
At So WHAT, we believe getting dressed for the gym shouldn't come with compromises.
That's why we design plus-size clothing with the person wearing it in mind, from the fit and proportions to the details that make a piece comfortable enough to actually live in.
Whether you're heading to the gym for your first workout, getting back into your routine or you're already a regular, here's what to look for when building your gym wardrobe.
1. Start With the Right Fit, Not Just the Right Size
There's a difference between finding a garment in your size and finding a garment that actually fits you well.
For gymwear, that distinction matters even more.
Your T-shirt needs enough room through the chest and midsection to let you move naturally, while the sleeves and shoulders should allow you to raise and move your arms without constantly pulling at the fabric.
At the same time, going several sizes up isn't automatically the answer. An excessively loose T-shirt can get in the way during movement and lose the clean silhouette you're looking for.
The goal is simple:
Enough room to move. Enough structure to feel put together.
That's the approach we take when designing our plus-size fits at So WHAT.
2. Choose a T-Shirt That Moves With You
A good gym T-shirt needs to do more than simply look good on a hanger.
You're going to stretch, walk, lift, bend, sit and move in it. Your T-shirt should be able to keep up.
Our WHATZ Plus Size Honeycomb Dry Fit Solid Round Neck T-Shirt is designed with active days in mind, giving you a versatile option that works for workouts while remaining easy to wear beyond the gym.
- A few things to look for in your gym T-shirt:
- A comfortable fit around the chest and stomach
- Sleeves that allow natural arm movement
- A length that stays comfortable while moving
- A neckline that sits comfortably without feeling restrictive
- A fabric suited to an active lifestyle
And perhaps most importantly, you should feel comfortable wearing it.
Gymwear doesn't need to be complicated. The right T-shirt can be the foundation of your entire workout wardrobe.
3. Don't Forget the Bottom Half
When choosing gymwear, it's easy to focus entirely on the T-shirt.
But your track pants can make just as much difference to how comfortable you feel during a workout.
A good pair should give you enough room to move through the waist, hips and thighs while still giving you a clean, considered fit.
Our SO WHAT Plus Size Essential Track Pant is designed as an everyday staple, something you can wear for your workout, your walk to the gym or simply when you're having a relaxed day.
If you prefer a sportier look, our WHATZ Plus Size Side Stripe Activewear Trackpants add a little more visual detail while keeping the outfit easy and functional.
The key is to find track pants that don't make you think about them while you're wearing them.
That's when you know the fit is doing its job.
4. Think About How You Actually Move
One of the biggest mistakes people make when choosing gymwear is judging the fit only while standing still.
Try thinking about how you'll actually wear the clothes.
Will you be:
- Lifting weights?
- Walking on a treadmill?
- Cycling?
- Stretching?
- Doing strength training?
- Moving between different exercises?
Your clothes need to accommodate movement rather than simply look good in a mirror.
This is one reason fit matters so much to us at So WHAT.
We don't believe plus-size clothing should simply be a larger version of a standard garment. The proportions, comfort and overall experience need to be considered for the person wearing it.
5. Build a Gym Wardrobe That Works Harder
You don't need an entirely separate wardrobe just for the gym.
Start with a few versatile pieces that you genuinely enjoy wearing.
A simple rotation could be:
The Everyday Workout
Dry Fit T-shirt + Essential Track Pant + Trainers
A straightforward combination for your regular gym sessions.
The Sportier Look
Dry Fit T-shirt + Side Stripe Activewear Trackpant + Trainers
A little more athletic, while still keeping the outfit clean and uncomplicated.
The Off-Duty Workout Look
T-shirt + Track Pants
Perfect for travelling to the gym, running errands afterwards or simply having a comfortable day.
The best gym wardrobe is one that fits naturally into your life.
6. Your Size Should Never Be an Afterthought
When shopping for gymwear online, choosing the right size can sometimes feel like the hardest part.
Don't rely only on the size you usually buy from another brand. Sizing can vary significantly between brands and even between different styles.
Instead, take a few minutes to check the measurements for the specific garment you're buying.
At So WHAT, we offer extended sizing because we believe more people deserve access to clothing that has been thoughtfully designed around them.
Take a look at our size chart before ordering and choose the size that corresponds best with your measurements and preferred fit.
If you're between sizes or unsure about what to choose, our team is always here to help.
Because finding your size shouldn't feel like guesswork.
7. Gymwear Should Make You Feel Ready, Not Self-Conscious
There's something important about putting on an outfit that fits properly.
You stop adjusting it.
You stop wondering if it's pulling somewhere.
You stop thinking about whether the sleeves are too tight or the waistband is uncomfortable.
And you can get on with your day.
That's what we want our clothing to do.
We're not here to tell you that you need to dress a certain way because of your size. We're here to create clothes that give you options, clothes that are made to fit, made to move and made to be worn.
Your Workout. Your Fit. Your So WHAT.
There isn't one "right" way to dress for the gym.
You might prefer a relaxed T-shirt and track pants. You might like a more athletic look. You might wear the same black T-shirt every week because you know it works for you.
That's completely fine.
What matters is that your clothes work for you.
At So WHAT, that's always been at the heart of what we do.
We create premium plus-size clothing with thoughtful fits, quality you can feel and the everyday needs of our customers in mind, because your size shouldn't limit your choices.
Find your fit. Choose your style. Get moving.
