Finding the right workout shorts can feel like an endless trial of rides, chafed thighs, and pockets that swallow your phone. The perfect pair disappears on your body—light, breathable, and tuned exactly for the motion you’re doing, whether that’s a heavy squat, a long run, or a midday stretch. After digging through hundreds of reviews and real-user feedback, I’ve narrowed the field down to the pairs that actually deliver on their promises.
I’m Mohammad — the founder and writer behind ProteinJug. I analyze gear through the lens of material science and real-world use, comparing fabric blends, inseam lengths, and pocket designs to separate marketing fluff from genuine performance.
This guide breaks down the seven top contenders for the best shorts for working out, covering everything from moisture-wicking polyester blends to the debate between lined and unlined cuts.
How To Choose The Best Shorts For Working Out
The right pair depends on your primary activity—running demands different features than weightlifting, and lounging shorts rarely hold up under heavy sweat. Focus on these three factors before buying.
Inseam Length and Mobility
A 7-inch inseam strikes a balance between coverage and freedom. 9-inch shorts sit closer to the knee, offering more modesty but can bunch up during deep squats. Shorter 5-inch inseams maximize airflow but may ride up during leg press. Match the inseam to your gym’s dress code and your preferred range of motion.
Liner vs. Linerless
A built-in compression liner eliminates the need for separate underwear and prevents chafing—ideal for running and cycling. Linerless shorts give you the freedom to choose your own base layer, which is preferred by lifters who want a looser feel. The trade-off is that linerless models require more careful sizing to avoid sheer fabric.
Pocket Security
Nothing ruins a set like your phone slapping against your shin mid-lunge. Look for a zippered or internal phone pocket on the right side—this keeps your device secure during dynamic movement. Open mesh pockets are fine for casual wear but fail during sprints or box jumps.

In‑Depth Reviews
1. CRZ YOGA Men’s Linerless Workout Shorts 9″
The CRZ YOGA 9-inch linerless shorts have become the go-to alternative for guys who swear by Lululemon’s T.H.E. Short but refuse to pay triple digits. The fabric is featherlight, dries rapidly, and the zippered side pocket fits a Pixel 5a with case without any bulge. Multiple large pockets mean your phone, keys, and gym card all have a dedicated home.
User feedback is consistently positive on durability: these shorts survive MMA rolling, runs, and frequent washing without pilling or losing shape. The 9-inch inseam provides generous thigh coverage, which is ideal for lifters who want to avoid the “short shorts” look while still maintaining full squat mobility.
The dark gray color is versatile enough for post-gym errands, and the waistband sits flat without pinching. The only real caveat is that they are linerless, so you need to wear separate compression shorts or underwear unless you prefer a looser feel during dynamic movement.
Why it’s great
- True to size, breathable, and soft for all-day wear
- Zippered pocket secures large phones
- Excellent Lululemon dupe at a fraction of the price
Good to know
- Linerless design requires separate base layer
- 9-inch inseam may feel long for shorter runners
2. Under Armour Men’s Launch Run 7 Inch Unlined Shorts
The Under Armour Launch Run shorts are engineered specifically for runners. The 100% polyester woven fabric is ultralight, and the super-breathable mesh panels along the side provide targeted ventilation where you need it most. This is a linerless model, so you control your base layer, which gives you the freedom to wear compression shorts or go commando based on your comfort.
Reviewers note the 7-inch inseam hits right above the knee for most men—long enough to prevent thigh chafing without restricting stride. The right-side internal phone pocket is a standout feature for runners who hate bouncing pockets. The waistband uses a soft knit material with an internal drawcord for a locked-in fit that doesn’t dig in.
Another smart detail is the main body fabric contains at least 90% recycled polyester, making this a more sustainable choice. Users confirm it survives weekly wash-and-dry cycles without shrinking or fraying. The only reported issue is that the shorts run slightly small, so consider sizing up if you are between sizes.
Why it’s great
- Ultra-breathable mesh panels for intense runs
- Internal phone pocket stays secure during sprints
- Made with recycled polyester
Good to know
- Runs small—size up if between sizes
- Linerless—no built-in compression
3. maamgic Gym Shorts for Men 7 Inch Inseam with Liner
The maamgic 7-inch shorts offer the best of both worlds: a loose outer shell with a built-in compression liner. The 2-in-1 design eliminates the need for separate underwear, which is a major convenience for gym-goers who want a single-pull solution. The fabric is thick and opaque—no see-through worries even during deep bends—and the zippered pocket is a welcome addition for securing valuables.
Customer reviews praise the aesthetic design and the stretchy, breathable material that feels premium without the premium price tag. The discreet drawstring keeps everything in place without creating a bulge. For tall guys (6’4”), the size range accommodates without the shorts riding up, although the liner may feel slightly loose on very thin builds.
The primary criticism is that the inner liner could be more snug for running, as some users reported concerns about chafing during longer runs. For general gym work, lifting, and casual wear, these shorts are a strong mid-range pick. They wash well and retain color vibrancy after multiple cycles.
Why it’s great
- Built-in compression liner for chafe-free movement
- Thick, non-see-through fabric
- Stylish with versatile color options
Good to know
- Liner may not be snug enough for high-mileage runners
- Slightly higher entry price than basic mesh shorts
4. Under Armour Men’s Train Stretch 2.0 Shorts
The Under Armour Train Stretch 2.0 is a dedicated training short built for the weight room. The stretch fabric moves with you through squats, lunges, and deadlifts without restriction, while the inner stretch liner provides light compression and eliminates the need for extra underwear. Users consistently describe them as “not heavy” and “very breathable”—they won’t trap sweat like cotton shorts do.
The regular fit is true to size, and the 2-in-1 liner gives you the support of compression shorts without a tight binding feel. The waistband sits flat and stays comfortable through heavy leg days. Several buyers mention that these have become their new favorite training shorts, replacing other brands.
The main caution is sizing: if you are on the smaller side, consider sizing down, as some users found the shorts a bit roomy. The liner’s stretch can accommodate different thigh sizes, but the outer shell is cut generously. Overall, a solid mid-range option for anyone who wants a dedicated pair for multi-purpose training sessions.
Why it’s great
- 4-way stretch fabric for unrestricted lifting
- Built-in liner for support without extra layers
- Breathable and moisture-wicking
Good to know
- Runs a bit large—size down for a tighter fit
- Limited pocket options for phones
5. Nike Mens Pro Training Compression Shorts
The Nike Pro Compression Shorts are a staple for runners and lifters who want a second-skin fit. The compression fabric provides muscle support and helps reduce vibration during high-impact movement, which can aid in recovery. Users report zero chafing issues even during long runs, and the material is durable enough to survive regular use.
The mid-thigh length offers good coverage without extending to the knee, which keeps mobility high. The waistband stays put without rolling, and the flatlock seams prevent irritation. For anyone recovering from a pulled muscle or glute injury, these shorts offer a supportive layer that can be worn under looser shorts or on their own.
One caveat: the length is shorter than some expect—it sits mid-thigh rather than just above the knee. This is great for mobility but may feel too short for men who prefer longer compression shorts. The quality of the fabric, stitching, and overall construction is excellent for the price, making these a reliable choice for dedicated athletes.
Why it’s great
- Excellent muscle support and chafe protection
- Durable construction that holds up to frequent washing
- Flatlock seams prevent irritation
Good to know
- Shorter mid-thigh cut—may feel too brief for some
- Not a standalone short for casual wear
6. KCVENN Men’s 7 Inch Inseam Athletic Shorts
The KCVENN 7-inch athletic shorts are a solid entry-level choice for guys who want a comfortable linerless short for both the gym and lounging. The fabric feels silky and soft, similar to high-end golf shorts, and it washes and dries well without shrinking. The elastic waist with an internal drawstring allows for a customized fit that works well for looser preferences.
Buyers consistently mention that these shorts look and feel more expensive than they are. The 7-inch inseam hits just above the knee for most builds, and the generous cut provides freedom of movement for lifting and everyday errands. They also make a great gift—the silky texture and clean look appeal to a wide range of guys.
The biggest weakness is pocket security: the open hand pockets are fine for keys and a wallet but are not secure for a phone during sprints. If you use these for high-intensity cardio, your phone will bounce. They are best suited for weightlifting, casual wear, and low-impact activities where you don’t need a zippered pocket.
Why it’s great
- Silky, comfortable fabric that feels premium
- Good fit for tall guys (5’11”+)
- Washes and dries well without fading
Good to know
- Open pockets not secure for intense cardio
- Linerless—requires separate underwear
7. OYGSieg 6 Pack Mens Mesh Athletic Basketball Shorts
The OYGSieg 6-pack mesh shorts are the volume play. For the price of a single premium pair, you get six shorts in a range of colors, making them ideal for guys who want a no-fuss rotation for the gym, lounging, or sleep. The mesh fabric is lightweight and breathable—perfect for hot weather basketball or casual wear—and the size chart is accurate for larger builds, including 360-pound users.
Reviewers consistently note that the shorts hold up well after washes without shrinking or fading. The deep pockets are a bonus for holding keys and a wallet, and the true-to-size fit means you can order your usual size without guesswork. For the price per unit, the value is hard to beat if you need multiple pairs.
The main complaints are cosmetic: the drawstring is thin and feels weak compared to the rest of the construction. A thicker string would improve the overall feel. Also, some tall users (6’0” and above) found the length a bit short—the legs go to right above the knee rather than providing full coverage. If you value a longer inseam, these may feel too brief.
Why it’s great
- Excellent budget-friendly value—six pairs for the price of one
- Lightweight and breathable mesh ideal for hot weather
- True-to-size fit with accurate size chart
Good to know
- Thin drawstring feels flimsy
- Inseam may be too short for tall men
