Gym shorts should be the last thing you think about mid-set. If you're adjusting the hem between reps, you're wearing the wrong pair — here's what actually makes a pair of gym shorts work.
What Makes Gym Shorts Actually Work for a Workout
She's three minutes into a set of box jumps when she realizes she hasn't thought about her shorts once. No tugging at the hem, no adjusting the waistband between reps. That's not an accident — that's what a gym short is supposed to do, and most of them don't.
Gym shorts are built for one purpose: unrestricted movement during exercise, with a length, waistband, and fabric weight suited to high-intensity motion rather than everyday wear. That distinction matters more than it sounds — a cotton short and a true gym short can look identical on a hanger and perform completely differently mid-workout. According to SELF, women consistently rank fit and coverage as the top factors in whether they actually wear their workout clothes or leave them in the drawer.
At Glossy, we think the search for gym shorts is really a search for something you forget you're wearing. That starts with the collection you're pulling from — our athleisure collection was built around exactly that idea.
What to Look For in a Pair of Gym Shorts
The best gym shorts for women hit a specific combination — length that doesn't restrict a squat or a stride, a waistband that stays put without digging in, and fabric that handles sweat without going sheer. Miss any one of those and the rest doesn't matter.
- Length — Anything from a 3-inch to 5-inch inseam works for most training; shorter lengths favor running and HIIT, while a longer inseam suits studio classes and low-impact days. The right length lets you lunge, squat, and stride without pulling at the hem.
- Waistband — High-waisted gym shorts sit above the navel and stay there through burpees and sprints, unlike low-rise styles that slide down mid-set. A wide, structured band is what actually holds — thin elastic just stretches out over time.
- Fabric — Moisture-wicking, four-way stretch fabric with a built-in liner keeps you dry and prevents chafing on longer sessions. Weight matters too: too thin and it goes sheer when you bend over, too heavy and it restricts range of motion.
According to Women's Health, waistband slippage remains one of the most common complaints across activewear categories — not just leggings. It's why we engineer the waistband on every Glossy bottom to hold compression rather than just look the part.
Once you know what to look for, the next question is which type of short actually matches your workout.
Running Shorts, Training Shorts, and Everything In Between
Not every gym short is doing the same job. The right one depends on what you're actually training for that day.
Running shorts — Built lightest, often with a side split or built-in brief liner, running shorts prioritize stride length over coverage. Look for a shorter inseam and a wide waistband that won't bounce on longer runs.
High-waisted training shorts — For strength training, HIIT, or the gym floor, high-waisted gym shorts with real compression are the move. They stay put through squats, deadlifts, and box jumps because the waistband is doing structural work, not just sitting there.
Compression-lined shorts — A hybrid option, often worn over a legging for extra coverage during outdoor training or on cooler mornings. Some women layer a pair of shorts over a legging for warmth without losing range of motion — Glossy's athleisure legging works well underneath for exactly that reason.
The honest answer: most active women end up owning two or three types and rotating based on the workout, not the outfit. ACE notes that clothing which restricts range of motion measurably changes exercise form over time — one more reason fit isn't a cosmetic decision.
How to Wear Gym Shorts Off the Gym Floor
Gym shorts stopped being gym-only a while ago. The same pair that gets you through a lifting session works just as well for the fifteen minutes after.
Running errands after a morning workout doesn't require a full outfit change — a high-waisted short, an oversized tee knotted at the waist, and slides is a complete look, not a compromise.
For travel days, gym shorts paired with a loose layer up top move through airport security lines and long flights better than jeans ever will. If you're building that look, pairing an oversized tank with fitted bottoms is one of the easiest combinations to get right.
Our take: the shorts are rarely the hard part of a gym-to-street outfit — the top is. For a full breakdown of how to build the rest of the look, see our complete guide to gym outfits for women.
The Glossy Edit: What We Look for in a Gym Short
When we evaluate a short before it makes it into the Glossy lineup, three things get tested before anything else: waistband hold, fabric opacity under stretch, and how it performs after the twentieth wash — not the first.
A waistband should compress without leaving a mark. That's the difference between a short that supports your core and one that just sits on top of it.
Fabric should stay opaque through a full squat, not just a standing pose in the mirror. If you have to double-check in a fitting room mirror, it's already failed the test.
And it should still look and perform the same after a season of workouts — because a short that falls apart in eight weeks isn't actually cheaper than one that lasts two years. That's the difference between activewear you own and activewear you reach for every time.
The right gym shorts don't ask you to think about them mid-set. Find the pair that disappears the moment you start moving — explore the full collection and build from there.
FAQ
What length should gym shorts be?
Most training and HIIT workouts work best with a 3 to 5-inch inseam, since anything longer can bunch up during squats or lunges. Running favors the shorter end of that range, while studio classes and low-impact days can handle a slightly longer inseam for coverage.
Are high-waisted gym shorts better than low-rise for working out?
Yes, for most training. High-waisted gym shorts sit above the navel and stay in place through squats, sprints, and burpees, while low-rise styles tend to slide down mid-set. The higher waistband also adds light core compression, which many women find more comfortable during heavy lifts.
Can I wear running shorts for weightlifting?
You can, but they're not built for it. Running shorts prioritize a light, unrestricted stride over the structured, compression waistband that strength training needs, so they're more likely to shift or ride up during squats and deadlifts. A high-waisted training short is the better fit for the gym floor.
How do I stop gym shorts from riding up?
Ride-up usually comes down to two things: a waistband that's too thin to hold its position, and fabric with too little structure. Look for a wide, high-set waistband and a four-way stretch fabric with real compression — the short should move with your body instead of shifting on top of it.
What fabric is best for gym shorts?
Moisture-wicking, four-way stretch fabric with a built-in liner is the standard for a reason — it manages sweat, prevents chafing, and holds its shape through repeated washes. Fabric weight matters too: it should be substantial enough to stay opaque through a full squat, not just a standing pose.
Can I wear gym shorts outside the gym?
Absolutely — gym shorts have become a genuine athleisure staple, not just workout gear. Paired with an oversized tee or tank and slides, they work for errands, travel days, and casual outings just as well as they work for training.
