Training shorts live or die by their waistband tension, pocket security, and fabric breathability during a leg-day sweat session. Nothing kills a squat set faster than a phone sliding out of a shallow pocket or a liner bunching up mid-rep.
I’m Mohammad — the founder and writer behind ProteinJug. I spend my time dissecting fabric blends, compression panel construction, and inseam lengths across hundreds of training shorts to separate the gear that holds up from the gear that gives out after three washes.
This guide breaks down the top contenders in the shorts for training space, comparing 7-inch inseams, 2-in-1 liners, and moisture-wicking Dri-FIT builds so you can pick the pair that matches your movement style.
How To Choose The Best Shorts For Training
Training shorts are not interchangeable with casual basketball shorts or swim trunks. The wrong pair introduces distractions — bunching liners, damp fabric that stays wet, or pockets too shallow for a smartphone. Focus on three core specs: inseam length, liner construction, and fabric weave.
Inseam Length & Mobility
A 7-inch inseam is the sweet spot for most gym movements. It covers enough thigh to prevent fabric ride-up during squats and lunges without restricting knee flexion or looking overly baggy. Shorter 5-inch inseams suit runners who prioritize ventilation, while 9-inch versions work better for taller athletes who want full thigh coverage.
Liner vs. Unlined Design
2-in-1 shorts with a built-in compression liner eliminate the need for separate underwear and reduce chafing during high-rep training. The liner must be snug but not constrictive — loose liners bunch and cause friction under the outer shell. Unlined shorts require moisture-wicking briefs and offer more airflow for hot-weather runs.
Pocket Security & Storage
Zippered pockets are non-negotiable for anyone who trains with a phone or keys. Standard open hand pockets let items fall out during burpees or box jumps. Look for a right-side internal phone pocket integrated into the waistband — it secures the phone flat against the hip, reducing bounce during dynamic movement.

In‑Depth Reviews
1. Nike Dri-Fit Flex Woven Shorts 7inch
Nike’s Dri-FIT Flex Woven fabric delivers the lightest hand feel in this lineup — a tightly woven shell that breathes without the limp drape of cheap mesh. The 7-inch inseam hits mid-thigh and allows unrestricted knee drive during tennis lunges or box jumps. Pocket depth is adequate for a phone and keys, and the elastic waistband with internal drawcord stays put under load.
One unit arrived with a rip in the leg, suggesting occasional QC inconsistency, but replacements resolve the issue. After several washes the fabric holds its shape without pilling, though the material is noticeably thinner than traditional gym shorts — better for summer training than cold-weather layering. Multiple users report the shorts feel “disappearing light” during dynamic movement.
The flex woven construction gives a structured look that transitions from gym floor to a quick errand without looking sloppy. For athletes who prioritize freedom of movement and fast sweat evaporation over insulation, this is a top-tier shell. Pair with compression briefs if you prefer additional support.
Why it’s great
- Ultralight woven fabric with instant sweat wicking
- Secure pockets with reliable drawcord waist
Good to know
- Fabric is thin; best for warm-weather training
- Occasional QC issues reported with seam integrity
2. Under Armour Men’s Launch Run 7 Inch Unlined Shorts
Under Armour’s Launch Run shorts hit the ideal balance of weight, breathability, and pocket design. At just 4.96 ounces the 100% polyester woven fabric is almost weightless, but the real differentiator is the super-breathable mesh paneling along the sides — it dumps heat during high-intensity intervals and prevents that swampy cling feeling. The 7-inch inseam is long enough to avoid ride-up on leg day without restricting stride.
The soft knit waistband with internal drawcord delivers a secure fit that doesn’t dig in during loaded carries, and the right-side internal phone pocket keeps a smartphone flat against the hip — no bounce even during sprints. Open hand pockets are deep enough for keys but lack zippers, so expect items to shift during dynamic movement. The build uses at least 90% recycled polyester, which adds environmental consideration without sacrificing performance.
Sizing runs slightly small — users who normally wear large should consider extra-large for a relaxed fit. The unlined shell pairs best with moisture-wicking briefs, and the low-stretch fabric maintains its shape through repeated wash cycles. For runners and gym goers who want one pair that does both well, this is the most versatile pick in the roundup.
Why it’s great
- Ultralight 4.96 oz build with mesh ventilation panels
- Internal phone pocket eliminates bounce during runs
Good to know
- No zipper on open hand pockets
- Sizing runs small; size up for a relaxed fit
3. HOPLYNN 5 Pack Mens 2 in 1 Running Shorts with Liner
HOPLYNN’s five-pack strategy eliminates the decision fatigue of buying single pairs — you get a full rotation for the cost of one premium short. Each pair features a built-in compression liner that provides privacy during deep squats and eliminates the need for separate underwear. The outer shell uses a thick yet breathable woven fabric that resists showing sweat patches and holds up to frequent washing without fading or pilling.
Pocket design is a highlight: deep front hand pockets accommodate an iPhone 15 Pro with case, and a small back zippered pocket secures keys or cards. The inner liner material feels cool to the touch against the skin, though some users note the seams run internally and may cause minor irritation during very long runs. Sizing runs slightly small — a 5’10”, 175lb athlete with a 32-inch waist needs large for a comfortable fit.
The generic unbranded look works well for gym rotations but lacks the style factor of Nike or Under Armour. For the price, the material density and liner construction punch well above their weight class, making this the most economical way to stock a training wardrobe without sacrificing performance essentials.
Why it’s great
- Five pairs at a single-pair cost; full rotation ready
- Compression liner eliminates extra underwear
Good to know
- Internal seams may irritate on long runs
- Slightly thicker outer shell; less airflow than mesh
4. Maamgic Gym Shorts for Men 7 inch Inseam with Liner
Maamgic’s 2-in-1 shorts combine a thick, non-see-through outer shell with a full compression liner — a design that eliminates transparency worries during deep stretches and provides moderate muscle support. The 7-inch inseam hits a versatile mid-thigh length suitable for both gym floor work and casual wear. The drawstring sits inside the waistband for a clean look, and the stretch woven fabric accommodates dynamic hip movement without resistance.
The outer material feels denser than typical running shorts, closer to swim trunk weight, which adds durability but reduces breathability in hot conditions. A zipper pocket on one side secures a phone or keys, and the compression liner offers good support for average-to-athletic builds. However, thinner individuals report the liner lacks sufficient snugness, leading to fabric bunching and potential chafing during runs — a notable issue for runners with slim thighs.
At a mid-range price point, the build quality rivals premium brands like Lululemon for a fraction of the cost. Users consistently praise the sharp silhouette and color options. For gym-goers who prefer the security of a built-in liner and don’t need extreme ventilation, this is a well-rounded daily driver.
Why it’s great
- Thick outer fabric eliminates see-through during squats
- Premium feel and fit at a mid-range price
Good to know
- Compression liner may not be snug enough for thin builds
- Heavier fabric limits ventilation in high heat
5. Nike Mens Pro Training Compression Shorts
Nike’s Pro Compression Shorts are the gold standard for athletes who want muscle stabilization and chafe protection during high-rep training or long runs. The Dri-FIT knit fabric delivers four-way stretch that hugs the quad and glute without restricting range of motion — ideal for sprints, box jumps, and loaded squat work. The compression fit also provides light proprioceptive feedback, helping muscle groups feel engaged and supported throughout the movement.
The 5-inch inseam sits mid-thigh, which is shorter than the 7-inch training shorts in this guide and may feel too brief for athletes expecting knee-length coverage. The waistband stays flat under a belt or singlet, and the flat-lock seams reduce friction against the skin — no hot spots even during hour-long sessions. Users report excellent durability across dozens of wash cycles, with the fabric retaining its compression tension without bagging out at the knees.
These shorts function best as a base layer under loose shells or alone for activities that demand full unrestricted mobility. They are not designed for pocket storage — no phone or key compartments — so plan to carry items separately. For athletes whose priority is muscle support and zero chafe, these are the most focused compression option available.
Why it’s great
- Superior compression for muscle support and chafe prevention
- Durable Dri-FIT fabric retains shape after repeated wash
Good to know
- No pockets for phone or keys
- 5-inch inseam is shorter than typical training shorts
6. CE’ CERDR Women’s Athletic Workout Short High Waisted Elastic Running Shorts with Pockets
CE’ CERDR’s high-waisted shorts address a persistent women’s training pain point: waistbands that roll down during movement. The wide elastic band stays put over the hips and provides gentle compression around the midsection — comfortable enough for a pregnant belly at 165-170 lbs, yet secure enough for high-knee drills. The built-in inner shorts offer additional coverage and prevent ride-up without adding bulk.
The outer fabric is soft, stretchy, and lightweight, with colors that stay vibrant after machine washing. Zippered pockets on both sides fit an iPhone 16 Pro Max without bulging, making these practical for phone-free running. The 3-inch inseam is on the shorter side, providing ample ventilation but limiting modesty for those who prefer more thigh coverage. Sizing consistency has minor variation: some shorts in a multi-pack fit perfectly while others run tight in the waist.
For the price point, the combination of a non-constrictive high waist, zippered storage, and built-in liner makes these a strong contender in the women’s training category. Runners and gym-goers who prioritize pocket security and torso coverage will find these deliver reliable performance without breaking the budget.
Why it’s great
- High-waisted band stays put during dynamic movement
- Zippered pockets secure large smartphones
Good to know
- Short 3-inch inseam; less coverage than standard shorts
- Slight sizing inconsistency across different colors
7. 2 Pack Mens Athletic Shorts Quick Dry 7 Inch Running Shorts Breathable Mesh Gym Workout Shorts with Zipper Pockets
This two-pack delivers the essentials — quick-dry mesh fabric, zippered pockets, and a 7-inch inseam — at a price point that makes strict budgeting easy. The mesh weave maximizes airflow, keeping the skin cool during outdoor runs or intense cardio sessions. The waistband is thick enough to hold the shorts in place during dynamic movement, and the internal drawcord adds a secondary security layer for waist adjustment.
Reflective patches on the front and rear improve low-light visibility, a safety feature typically absent at this price tier. Zippered pockets on both sides secure a phone, keys, or wallet without bounce. The fit runs slightly large — a 6’0″, 200 lb athlete wearing large could have fit a medium — so sizing down may improve the silhouette for those who prefer a less baggy look.
The fabric shows its budget roots after multiple wash cycles — lighter colors may fade faster than premium alternatives, and the mesh structure is less durable than woven options. For walkers, casual gym-goers, or anyone building a training wardrobe from scratch, these shorts offer the most storage and ventilation for the lowest investment. They are not built for high-abrasion CrossFit or heavy barbell work.
Why it’s great
- Two pairs with zippered pockets at a budget-friendly price
- Reflective patches improve low-light visibility
Good to know
- Looser fit; sizing down recommended for a tailored look
- Mesh fabric less durable than woven; prone to fading
