Training shorts live in a harsh environment—sweat-soaked squat sets, explosive box jumps, and pavement-pounding miles. The wrong pair binds your quads, traps moisture, or dumps your phone mid-rep. Finding a pair that breathes, stretches, and pockets securely is the difference between a great session and a frustrating one.

I’m Mohammad — the founder and writer behind ProteinJug. My buying guides focus on the real-world durability of workout gear, analyzing moisture-wicking fabrics, zipper pocket usability, and inseam measurements to ensure every short can handle repeat cycles in the gym and the wash.

This guide breaks down the top contenders across value, features, and build quality to help you lock in the best men’s training shorts for your routine.

How To Choose The Best Men’s Training Shorts

Not all gym shorts are built the same. A pair designed for yoga won’t survive a heavy deadlift session, and a thick cotton short soaks through before your first set. Focus on three core pillars: fabric behavior, pocket architecture, and fit/liner type.

Fabric and Moisture Management

The most important job of a training short is to wick sweat away from the skin and dry quickly between sets. Look for polyester or nylon blends with mesh panels. Avoid 100% cotton for any session over 20 minutes—it holds moisture and chafes when wet. A fabric weight that feels light but not see-through offers the best of both worlds.

Pocket Security and Placement

Nothing kills a sprint like a phone bouncing against your thigh. Zipper pockets are the gold standard for training shorts, but the devil is in the details: a zipper that sits too close to the hand opening can scrape your knuckles. Deep, lined zipper pockets that lie flat against the leg are what you want. A single secure phone pocket is often more practical than two shallow ones.

Inseam and Liner Preference

Inseam length determines both range of motion and coverage. Seven inches is the universal sweet spot—it sits above the knee without riding up. Shorter 5-inch inseams offer more freedom for running but can expose chafe zones. For liners, a built-in compression layer reduces the need for separate underwear and prevents chafing during high-rep sets, but it can feel restrictive. Separate shorts without liners give you more control over support.

Best Overall

1. CRZ YOGA Mens 2 in 1 Running Shorts 7″

2-in-1 LinerQuick-Dry Fabric

The CRZ YOGA 2-in-1 shorts are the strongest all-rounder in this list, combining a lightweight outer shell with a built-in compression liner that eliminates the need for separate underwear. The 7-inch inseam hits just above the knee, offering full coverage during squats without restricting hamstring movement. Users consistently praise the flatlock seams and non-rolling waistband, two details that prevent irritation during high-rep sets.

The pocket layout is smart: a zippered rear pocket secures a phone while a side stash pocket handles keys or cards. The quick-dry polyester blend sheds sweat fast, making these viable for both gym sessions and post-workout errands. One reviewer noted that the liner runs slightly large and can bunch during deep squats, so sizing down if you are between sizes is a solid strategy.

For the mid-range price, you get compression-short performance without the premium Lululemon price tag. The CRZ YOGA shorts hold their shape after repeated wash-and-dry cycles, and the durable liner resists pilling better than many budget 2-in-1 designs. These are the shorts you grab when you need one pair to do everything from sprints to leg day.

Why it’s great

  • Built-in compression liner prevents chafing
  • Secure zipper pocket holds phone without bounce
  • Flatlock seams and non-rolling waistband

Good to know

  • Liner can bunch during deep squats
  • Limited color options compared to budget packs

2. MIER Men’s Workout Running Shorts 7 Inch

No-Liner Design7″ Inseam

The MIER Workout Running Shorts have a strong following among lifters who prefer a clean, non-cargo look without sacrificing pocket space. The dual-pocket system pairs a standard slash pocket on one side with a secure zippered pocket on the other, letting you separate keys from your phone. The fabric is a dense polyester that feels higher-quality than typical budget shorts—it drapes well and resists the cheap sheen that plagues many quick-dry options.

At 7 inches, the inseam sits at a modern length that flatters most builds without showing too much thigh. The elastic waistband with an internal drawstring keeps the shorts in place even when loaded with a phone and keys. One common note from users: the zippered pocket opening sits very close to the regular pocket, and the zipper pull can scrape the back of your hand if you reach in aggressively.

These shorts genuinely transition from gym to lounge. The fabric doesn’t wrinkle like the JWJ or Ultra Performance options, and the stitch quality holds up to twice-weekly washing. If you want premium-feeling fabric without paying premium prices and prefer to wear your own compression underwear, the MIER is the strongest no-liner choice in this roundup.

Why it’s great

  • High-quality fabric with good drape
  • Versatile dual-pocket system (slash + zipper)
  • True-to-size fit with secure waistband

Good to know

  • Zipper pull can scrape hand during deep pocket reach
  • No built-in liner

3. Under Armour Men’s Mk-1 Shorts

Brand TrustQuick-Dry Fabric

Under Armour doesn’t need much of an introduction, and the MK-1 Shorts deliver the brand’s signature moisture-wicking performance without any gimmicks. The fabric is a lightweight polyester blend that feels cool against the skin and dries rapidly—ideal for back-to-back sets or outdoor runs in humid conditions. Reviewers consistently mention that the fit is accurate to size and that the material holds its color well after multiple washes.

The MK-1 is a simpler short compared to the 2-in-1 options or the multi-pocket designs. There is no built-in liner and only standard side pockets. That simplicity makes these great for runners who prioritize low weight and no chafe over storage. One reviewer noted the shorts run slightly shorter than anticipated, so if you want full coverage on the quad, consider the inseam carefully—these sit closer to a 5-inch feel on taller frames.

These are not the best choice for weightlifters who need to load up pockets with a phone, keys, and a lifting belt. But for pure running, HIIT circuits, or any session where airflow matters more than storage, the MK-1 is a reliable piece of gear that you can count on for years.

Why it’s great

  • Proven UA moisture-wicking fabric
  • True-to-size fit and accurate color
  • Lightweight and comfortable for running

Good to know

  • Runs slightly short in length
  • No zippered pockets for secure storage

4. 2 Pack Mens Athletic Shorts 7 Inch

2-PackReflective Details

This 2-pack from an unbranded manufacturer punches well above its price point. Each pair features a breathable mesh construction that maximizes airflow—think of them as the sweat-wicking cousin of a classic basketball short. The 7-inch inseam offers a relaxed cut that doesn’t bind the thighs, and the elastic waistband with a functional drawstring keeps them planted during dynamic movement.

The standout feature here is the inclusion of reflective patches on both shorts. For anyone who runs or walks at dusk, this visibility boost is a genuine safety upgrade you don’t usually see on budget-friendly packs. The zippered pockets are deep enough for most phones, and the fabric dries in 20-30 minutes after washing. Reviewers mention that the shorts run slightly large—if you are between sizes, size down.

These are not the most stylish shorts, and the fabric has a thinner feel than the MIER or CRZ YOGA options. But for the per-short cost, you get two functional, breathable pairs that handle everything from casual gym sessions to morning runs. For budget-conscious shoppers, this is the value king.

Why it’s great

  • Excellent airflow with mesh construction
  • Reflective details for visibility
  • Great value for a two-pack

Good to know

  • Runs slightly large; size down if between sizes
  • Thinner fabric may show outlines in bright colors

5. JWJ Mens Athletic Gym Workout Shorts

5-PackLightweight Build

The JWJ shorts are designed for the guy who wants a bulk rotation—this is a pack that comes with multiple color options, letting you grab a fresh pair every day without thinking. The fabric is lightweight and airy, almost like a swim trunk in feel, which makes them a good choice for high-intensity cardio or hot-weather training. The zipper pockets are functional and secure, holding a phone and keys without bouncing.

There are trade-offs for the low per-short cost. The pockets are on the smaller side—a large phone like an iPhone Pro Max fits, but it is tight, and the zipper pull can scrape your knuckles. The material also wrinkles easily if you toss them in a drawer. Reviewers suggest sizing up, as the cut runs snug, particularly in the thigh area.

These are best used as a high-volume rotation for light gym work, casual wear, or as a backup pair for travel. The fit is not as refined as the MIER or CRZ YOGA, and the fabric does not feel as durable long-term. But if you are tired of doing laundry mid-week and want five pairs at a single order, the JWJ pack hits that note.

Why it’s great

  • Great color variety in a 5-pack
  • Ultra-lightweight and airy fabric
  • Zipper pockets offer secure storage

Good to know

  • Pockets are small; phone fit is tight
  • Fabric wrinkles easily; runs snug in thighs
Budget 3-Pack

6. Ultra Performance 3 Pack Mens Shorts

3-PackSoft Drawstring

The Ultra Performance 3-pack is the definition of no-fuss casual training shorts. The material is soft, flexible, and comfortable against the skin—more aligned with lounge comfort than technical performance. The thick drawstring and functional zippers set it apart from the cheapest alternatives, and the fit is forgiving for athletic builds with thicker quads.

The key caveat is sizing. Multiple customers report that these shorts run large, so if you are between sizes, definitely size down. The fabric also attracts pet hair easily, which could be a dealbreaker for dog owners. These shorts are not designed for competitive use—the airiness is there, but the material lacks the dense weave you need for heavy barbell work or friction-heavy runs.

If your training shorts never see more than light lifting, treadmill jogs, and household lounging, this 3-pack offers tremendous per-short value. For crossfitters or runners who need a technical weave that stays dry under load, look to the CRZ YOGA or MIER options further up the list.

Why it’s great

  • Soft, flexible fabric for comfort
  • Good quality zippers and drawstring
  • Great price for a 3-pack

Good to know

  • Runs large; size down if between sizes
  • Fabric attracts pet hair
Lounge Fit

7. KCVENN 7 Inch Inseam Athletic Shorts

Loose FitSoft Fabric

KCVENN’s 7-inch shorts target the buyer who values soft-hand feel and a relaxed cut above all else. The material is noticeably softer than the mesh-based shorts in this roundup, making these ideal for lounging, sleeping, or light errands. The elastic waistband with an internal drawstring is comfortable enough to wear all day without digging in, and the 7-inch inseam gives enough length that compression shorts peek out only slightly.

Some reviewers note that these run small. If you are usually a large, consider sizing up if you want a looser fit. The quality is solid for the price, but the fabric is not as breathable as the mesh options. For heavy sweating sessions, you may want a dedicated athletic short instead. The color selection is practical and neutral, making them easy to pair with any gym top.

These are the shorts you reach for when you want to look put-together without sacrificing comfort. They hold up well in the wash and the colors fade minimally. For the guy who wants one pair that can do light gym work, errands, and bedtime in one purchase, the KCVENN shorts deliver exactly that.

Why it’s great

  • Very soft, comfortable material for all-day wear
  • Practical 7-inch length with neutral colors
  • Comfortable elastic waistband

Good to know

  • Runs small; may need to size up
  • Not as breathable as mesh-style shorts for heavy sweat

FAQ

Should I buy training shorts with or without a built-in liner?
It depends on your underwear preference and movement type. A built-in liner eliminates the need for separate compression shorts and prevents chafing during running. However, liners can bunch during deep squats or feel restrictive for some lifters. If you already own good compression shorts, a no-liner short like the MIER offers more flexibility.
How do I prevent my phone from bouncing in zipper pockets?
Bouncing occurs when the pocket is too shallow or the short lacks a secure inner sleeve. Look for shorts with a dedicated phone pocket that has a vertical orientation or an interior slip pocket that holds the device flat against the leg. The CRZ YOGA 2-in-1 and the Ultra Performance 3-pack both have zipper pockets that lie relatively flat during movement.
What does the 7-inch inseam mean for taller guys (6’0″ and above)?
For men 6’0″ and taller, a 7-inch inseam sits close to the knee or slightly above it, giving a modern, athletic look without showing too much quad. If you have long femurs, the shorts may ride up during seated leg curls. Some taller users in the JWJ and CRZ YOGA reviews noted that 7 inches worked well for their height, while others preferred a 5-inch cut for a more runner-oriented feel.

Final Thoughts: The Verdict

For most users, the best men’s training shorts winner is the CRZ YOGA 2-in-1 Running Shorts because it combines a secure compression liner, effective zipper pockets, and durable construction without demanding a premium price. If you want premium-feeling fabric without a built-in liner, grab the MIER Workout Running Shorts. And for a budget-friendly, high-airflow rotation that includes reflective safety details, nothing beats the 2 Pack Mens Athletic Shorts.
