Nothing derails a leg day like a waistband that rolls, a liner that bunches mid-squat, or paper-thin fabric that goes sheer the second you hit a hip hinge. The difference between a pair of bodybuilding shorts that works and one that frustrates you comes down to three things: the compression of the inner liner, the stretch recovery of the fabric under load, and the inseam length that keeps the hem from interfering with your starting position on the deadlift platform.
I’m Rikta — the co-founder and writer behind FitlyFast. I spent dozens of hours combing through spec sheets, customer reviews, and fabric composition data to understand exactly why some shorts feel restrictive on adductor machines while others disappear entirely the moment you start moving weight.
This guide breaks down seven top contenders to help you find the best bodybuilding shorts that actually hold up to heavy squatting, deep lunges, and high-volume training without riding up or wearing thin.
How To Choose The Best Bodybuilding Shorts
The wrong pair of shorts can steal your focus during heavy triples or make you self-conscious about fabric transparency during hamstring curls. Focus on these three factors to narrow your options quickly.
Liner Design and Compression Fit
A built-in compression liner saves you from wearing a separate pair of compression shorts, but not all liners are equal. The best bodybuilding shorts use a liner that is snug enough to support the adductors and glutes during deep squats but not so tight that it restricts blood flow or rolls up at the waistband. Check reviews for complaints about liner bunching — it’s the top reason lifers return shorts in this category.
Inseam Length and Freedom of Movement
For bodybuilding, a 7-inch inseam hits the sweet spot. A 5-inch short can ride up when you’re setting up for a deadlift, and a 9-inch short can catch on the edge of a squat pad or leg press platform. A 7-inch inseam stays put through the full range of motion and still gives your quads room to breathe. If you have very thick thighs, look for a slightly longer inseam with a tapered leg opening to prevent the hem from flaring.
Fabric Weight and Opacity
Heavier fabrics (around 200 GSM or more) resist transparency during stretched positions and hold their shape longer through repeated washing. Lighter fabrics dry faster but often lack the opacity needed for deep hip flexion. If you lift in a public gym, choose a fabric that lets you hit full depth on a squat without worrying about the material going see-through. Polyester-spandex blends with at least 8% elastane offer the best stretch recovery.

In‑Depth Reviews
1. HOPLYNN 5 Pack Mens 2 in 1 Running Shorts
$39.99$45.99as of Jun 29, 4:06 PMThis five-pack from HOPLYNN solves the single biggest pain point for lifters who train daily: running out of clean shorts mid-week. Each pair features a compression liner that provides enough support to skip underwear entirely, plus an integrated phone pocket within the liner that secures your device during leg press and cable work.
The outer shell uses a thicker, denser polyester-spandex weave that holds up to repeated squatting without losing its shape or becoming translucent. Reviewers consistently note that the material feels substantial — not flimsy or see-through — which is exactly what you want when you’re hitting depth in a busy gym.
At this price for five pairs, you’re getting a rotation-ready set that covers gym, running, and hiking without needing to wash after every session. Some users note the seams are internally finished, but no reports of irritation during heavy sets or long workouts.
Why it’s great
- Five pairs provide a full week’s rotation
- Thick fabric stays opaque in deep hip flexion
- Liner eliminates need for compression underwear
Good to know
- Internal seams may feel unfinished to some
- Generic unbranded design lacks style cachet
2. Nike Mens Shorts Dri-Fit Flex Woven Shorts 7inch
$39.99$50.00as of Jun 29, 4:06 PMThe Nike Dri-FIT Flex shorts use a woven fabric engineered specifically for multi-directional movement. The Flex construction stretches with your body during lateral lunges, walking dumbbell lunges, and cable crossover steps — movements where stiffer shorts can pull and restrict.
Hem vents allow unrestricted range for deep squat positions, and the Dri-FIT moisture management system pulls sweat away fast enough that you stay dry through superset circuits. The 7-inch inseam sits perfectly above the knee, avoiding the flared look that can get caught on equipment.
This is an unlined short, which means you’ll want to wear compression underneath if you prefer support during heavy leg work. The trade-off is a lighter, more breathable feel that works equally well for cardio finishers and HIIT sessions.
Why it’s great
- Flex fabric adapts to multi-directional movements
- Hem vents prevent restriction in deep squats
- Trusted Nike Dri-FIT moisture management
Good to know
- Unlined design requires separate compression
- Some users report sizing runs slightly small
3. Under Armour Men’s Launch Run 7 Inch Unlined Shorts
from $23.61as of Jun 29, 4:06 PMUnder Armour’s Launch Run shorts prioritize ventilation without sacrificing structural integrity. The woven polyester body is lightweight and durable, while super-breathable mesh panels along the side deliver targeted airflow where your body heat builds up most during back squats and deadlift warm-ups.
The sweat-wicking fabric dries remarkably fast, making these shorts a strong option for back-to-back training sessions or morning lifts that double as a quick run. The 7-inch inseam keeps the hem clear of your knees, and the internal phone pocket in the right hand pocket gives you secure storage during dynamic movement.
These shorts use at least 90% recycled polyester, which adds an eco-conscious edge without compromising durability. Because they are unlined, pair them with compression shorts if you want support through the hips and groin during heavy compound lifts.
Why it’s great
- Mesh side panels keep you cool during heavy sets
- Quick-dry fabric handles back-to-back sessions
- Eco-friendly recycled polyester construction
Good to know
- Unlined design expects separate compression layer
- Some customers find sizing runs small
4. CRZ YOGA Mens 2 in 1 Running Shorts 7″
$32.00as of Jun 29, 4:06 PMCRZ YOGA has built a reputation for delivering Lululemon-style performance at a fraction of the price, and their 2-in-1 running short is a textbook example. The ultralight feathery-fit fabric — 88% polyester blended with 12% spandex — gives you four-way stretch that moves with your body during leg presses and walking lunges without stretching out over time.
The compression liner is supportive enough for heavy squats, though some customers note that the liner can run slightly large and bunch during deep hip flexion. The 7-inch inseam and elastic waistband with internal drawstring keep everything locked in place through your entire workout.
Side pockets plus a right zipper pocket and an integrated phone pocket inside the liner give you plenty of secure storage. This is a strong contender if you want a lined short that feels barely there during conditioning work and still provides enough coverage for the main squat session.
Why it’s great
- Ultralight fabric feels barely noticeable during training
- Four pocket configuration keeps essentials secure
- Excellent value compared to premium athletic brands
Good to know
- Liner can bunch during very deep squats
- Limited color selection may not suit everyone
5. Maamgic Gym Shorts for Men 7 Inch Inseam with Liner
$32.99as of Jun 29, 4:06 PMMaamgic’s 7-inch lined shorts use a thick, heavy outer shell that customers consistently describe as non-see-through, even when stretched across the quads during thighs parallel squat position. The material has a dense structure reminiscent of swim trunks — it holds its shape and resists the thin, flimsy feeling that cheaper gym shorts often have.
The built-in compression liner provides full coverage, and the waistband uses an internal drawstring for a secure fit. Side zip pockets plus a lined phone pocket give you practical storage for gym essentials. The 7-inch inseam is long enough to stay put during deadlifts without interfering with knee drive.
One notable drawback is that the inner liner can feel loose for individuals with slimmer builds, potentially leading to chafing during high-rep sets or runs. This makes the Maamgic short better suited to lifters with more muscular legs who can fill out the liner properly.
Why it’s great
- Thick shell fabric stays opaque under tension
- Compression liner supports heavy compound lifts
- Multiple color options with functional pockets
Good to know
- Inner liner can be loose for slimmer builds
- Price feels higher than similarly spec’d options
6. FIONECA 3 Pack Men’s Athletic Running Shorts 5 Inch
$28.79$31.99Limited time dealas of Jun 29, 4:06 PMFIONECA’s 5-inch inseam shorts are built for lifters who run hot and prefer a shorter cut that keeps the knees completely exposed during squats and lunges. The 92/8 polyester-spandex blend delivers a lightweight, breathable feel that dries quickly between sets and during outdoor conditioning work.
All three deep pockets are zippered, which is a rare feature at this price point — your phone and keys stay locked in no matter how dynamic the movement pattern. The elastic waistband with drawstring provides a secure fit that doesn’t dig in, and the V-shaped side design adds some visual structure.
At a 5-inch inseam, these shorts ride higher than the 7-inch options in this guide. They work best for lifters who prioritize freedom of movement over thigh coverage and don’t mind showing more leg. If you do heavy pulling from the floor, the shorter inseam may ride up on setup.
Why it’s great
- Zippered pockets on all three pairs
- Lightweight fabric dries rapidly between sets
- 3-pack rotates easily through a training week
Good to know
- 5-inch inseam may ride up during deadlift setup
- Unlined design requires compression layer
7. Real Essentials Men’s 5 Pack 9″ Dry-Fit Shorts
$35.99as of Jun 29, 4:06 PMReal Essentials delivers a five-pack of 9-inch inseam dry-fit shorts that prioritize length and value above all else. The mesh-like fabric is lightweight and airy, making these shorts a good pick for casual wear, light gym sessions, and lounging. The 9-inch cut extends nearly to the knee, which some lifters prefer for coverage.
The material is noticeably thinner and silkier than the lined options in this guide. While it dries incredibly fast and feels soft against the skin, it does not offer the same opacity under deep stretch that thicker fabrics provide. If you plan to squat heavy, you may need to size down or layer with compression underneath.
The 5-pack pricing makes this essentially a no-brainer for building a baseline gym wardrobe. The pockets are functional but shallow for large phones. This is a solid choice for lifters who want a rotation-ready set for upper body days and casual wear, rather than a dedicated squat short.
Why it’s great
- Five pairs cover the entire training week
- Very affordable per-pair cost
- Comfortable for both gym and lounging
Good to know
- Thin fabric may become sheer during deep hip flexion
- Pockets are shallow for large smartphones
