After a sweaty gym session, your workout clothes aren’t exactly the freshest things in your closet. But the million-dollar question a lot of us wonder (and sometimes are too embarrassed to ask) is: how often should you wash workout clothes?
If you’re someone who works out daily, tossing your leggings, sports bras, and tees into the laundry basket every single time can feel like an endless cycle. On the flip side, re-wearing them without washing may seem like a time-saver—but is it actually okay?
So, grab your water bottle, settle in, and let’s break down the truth about workout laundry once and for all!
Why Washing Workout Clothes Matters More Than Regular Clothes
Unlike your everyday jeans or hoodie, workout clothes are designed to be skin-hugging and sweat-wicking. That means they’re in close contact with your body when you’re at your sweatiest, catching sweat, bacteria, and sometimes even dead skin cells. Ew, right?
Here’s why that matters:
- Bacteria + Sweat = Odor. Sweat itself doesn’t smell, but when it mixes with bacteria on your skin, that’s when the stinky magic happens. Re-wearing sweaty clothes just gives those bacteria more time to party.
- For skin health purposes. Dirty workout clothes can clog pores, leading to body acne, rashes, or irritation.
- Fabric longevity. Leaving sweat and oils in the fibers can actually damage your clothes over time, breaking down elasticity and wicking ability.
So even if the smell isn’t too bad, there’s more at stake than just odor control.
How Often to Wash Workout Clothes
Let’s get into the nitty-gritty. The answer to “how often to wash workout clothes” depends on how intense your workouts are and the type of clothing you’re using.
1. High-Intensity Workouts (Heavy Sweating)
Several types of high-intensity workouts include running, HIIT, spin classes, and hot yoga. These workouts leave your clothes drenched in sweat.
Re-wearing them without washing isn’t just gross—it can also be unhealthy for your skin. Sports bras, compression leggings, and sweat-soaked shirts should go straight into the laundry.
2. Moderate Workouts (Light to Moderate Sweating)
Examples of moderate workouts include weightlifting, brisk walking, Pilates, and casual cycling.
If you sweat only a little and your clothes still feel fresh, you might get away with wearing them one more time. However, items like socks and underwear-style leggings (with direct skin contact) should always be washed after each session.
3. Low-Intensity Workouts (Minimal Sweating)
If your workout routine is on the lighter side—like gentle yoga, stretching, meditation, or a light barre session—you usually don’t sweat much. That means your clothes don’t get as dirty as they would during a high-intensity workout. In this case, you can safely re-wear your gear one or two times before throwing it into the wash.
The key, however, is to care for them properly in between wears. Instead of tossing your tummy control leggings or top into a heap on the floor or leaving them crumpled in your gym bag, make sure to hang them up in a well-ventilated space.
Giving your clothes a chance to air out will keep them fresher for longer and ready for your next low-sweat workout.
4. Outer Layers
Outer layers like hoodies, light jackets, or track pants don’t usually come into direct contact with sweat the way sports bras or leggings do. Instead, they act more as a protective layer against the outside environment, which means they don’t get dirty as quickly.
Because of this, you don’t need to wash them after every use. In most cases, giving them a wash every three to five uses is more than enough.
If you notice visible dirt, stains, or any lingering odor, it’s time to toss them in the laundry, even if you haven’t hit that wear count yet.
5. Special Items
- Socks & Underwear: Always wash after every single use. No debates here.
- Sports Bras: Because they’re snug and sweat-absorbing, treat them like underwear and remember to wash after each use.
- Headbands & Caps: If sweat-soaked, wash after each workout. Otherwise, every couple of wears is fine.
Is It Safe to Re-Wear Workout Clothes Without Washing?
Here’s the honest truth: it can be safe (sometimes!). But it depends on the situation.
You can re-wear if:
- You did a low-sweat activity like yoga or light stretching.
- The clothes still smell fresh and feel dry.
- You aired them out properly (not stuffed into a gym bag).
You shouldn’t re-wear if:
- They’re visibly damp or smelly.
- You did a sweat-heavy workout.
- You’re prone to body acne, rashes, or sensitive skin.
If your workout top smells even slightly funky before you put it back on, skip it. That smell will only intensify once you start sweating again.
How to Maintain Workout Clothes Between Wears
We all know that tossing your workout gear in the wash after every single session isn’t always realistic—especially if you train almost daily. The good news is, there are a few tricks to keep your clothes fresh enough for a second wear without them turning into a bacteria party. Here’s how:
1. Air Them Out Immediately
The fastest way to ruin your workout clothes? Baling them up in your gym bag and forgetting about them until the next day. Sweat and bacteria trapped in a dark, damp space = instant odor factory.
As soon as you get home, take your clothes out of your bag and hang them somewhere with airflow. Even draping them over a chair is better than leaving them in a pile.
2. Use a Fabric Refresher
If your clothes smell just a little off, a fabric refresher can work wonders. A simple DIY mix of water and vinegar in a spray bottle helps neutralize odor-causing bacteria. Don’t worry, the vinegar smell disappears as it dries.
3. Rinse in Cold Water
If you’re short on time and not ready to do a full load of laundry, rinsing your clothes with cold water is a solid middle ground.
Cold water washes away fresh sweat and salts before they have a chance to settle into the fibers and cause permanent odor.
4. Spot-Clean Problem Areas
Sometimes, it’s not the whole outfit that’s dirty—it’s just certain spots, like the armpits, waistband, or crotch area.
How to do it:
- Dampen a cloth with a bit of water and mild detergent.
- Gently scrub the problem area, rinse with water, and let it air dry.
5. The Freeze Trick
Yes, it sounds unusual, but freezing your workout clothes really works. Place them in a resealable plastic bag, pop them into the freezer overnight, and by morning, odors are reduced because the bacteria are deactivated.
6. Choose High-Quality Activewear
One of the best ways to make your workout clothes last longer between washes is by choosing high-quality activewear. Premium fabrics are designed to wick sweat, resist odor, and maintain their shape even with frequent use.

FAQ
Is it okay to reuse workout clothes?
Yes, but only for light activities like yoga or stretching where you barely sweat. For intense workouts, it’s better to wash them right away to avoid odor and bacteria.
Can I wear the same sports bra for two workouts?
Nope. Sports bras absorb sweat and sit close to your skin, which makes them a breeding ground for bacteria. Always wash after one use.
Should workout clothes be washed immediately?
If your clothes are soaked after a tough session, wash them immediately. High-quality pieces like those from Diana Intimates are designed to handle frequent washes while staying comfy and durable.
