How to Choose Exercise Shorts for Men Based on Your Workout Type | Fit Matters

Buying the wrong pair usually means one of two outcomes: your running shorts bind on leg day, or your lifting shorts chafe on a long run. The fix for choosing exercise shorts for men based on your workout type is to stop looking at styles and start looking at what the shorts are actually built to do. Running, lifting, and hiking all place different demands on fabric, coverage, and support, so let the workout lead the decision.

What Inseam Length Do You Need?

Inseam length controls the trade-off between mobility and coverage. Shorter shorts give your legs full freedom and keep you cooler; longer cuts offer more coverage and a gym-ready look. The right length depends on the movement.

• Running and HIIT: 3–6 inch inseams. Short cuts let your stride open up and help with heat control. The Gymreapers Mesh Shorts, with a 4″ inseam, are a solid choice for high-intensity sessions.
• Weightlifting and CrossFit: 5–7 inch inseams. This range gives you room in the thigh for squats and deadlifts without a bunch of extra fabric. The Gymreapers Classic 6″ Training Shorts and the LSKD Challenger 6″ Performance Short sit right in this sweet spot.
• All-around gym use: 6–7 inches is the most-cited compromise between coverage and mobility, making it the most versatile length for mixed training days.

Which Fabric and Liner Work Best?

Fabric and liner choices determine how well a short handles sweat, movement, and chafing. Moisture management is non-negotiable for any workout that gets you sweating.

• Fabric: Prioritize polyester and spandex/elastane blends. They dry fast, breathe well, and stretch with your movement. Look for keywords like “moisture-wicking” or “quick-dry” on the label. The Ten Thousand Interval Short uses a performance shell with 4-way stretch, which is exactly the flexibility you want for dynamic training.
• Liner vs. linerless: Built-in liners (compression briefs) reduce chafing and add support for running and high-impact work. Linerless shorts are often preferred by lifters who want maximum freedom or plan to layer their own compression gear.

Fit matters too. You want a waistband that stays put during squats and a thigh that isn’t restrictive. The Fabletics Fundamental Short II is specifically noted for accommodating bigger thighs, so don’t assume a larger size fixes what a better cut should solve.

What About Pockets and Specific Workouts?

Pockets and durability features matter most when you’re away from a gym locker. A phone or keys bouncing in a loose pocket ruins a run, and a flimsy short won’t survive a bushwhack on a trail.

For running and hiking, secure or zippered pockets are a priority. The Ten Thousand Tactical Short uses a durable ripstop shell designed for training and adventure, while the Gymreapers Performance Shorts offer a lighter build for cardio days. For CrossFit and functional training, you want a short that can handle both lifting and dynamic movement, which is why the Ten Thousand Interval Short gets consistent “best overall” picks for its versatility.

If you’re building a short collection that covers multiple workouts, focus on the 6–7 inch length as your base. When you’re ready to see how top models compare on fabric, liner, and price, this roundup of the best exercise shorts for men breaks down the top contenders side by side.

Which Shorts Fit Your Primary Workout?

Once you identify your main training style, the choice becomes clearer. The table below maps the most common workout categories to the features that matter most.

The Ten Thousand Session Short is a strong running pick with its featherweight shell and ventilation. For lifting, the NOBULL Men’s Rep Short 6″ is a top recommendation. And if you want one pair that does everything reasonably well, a mid-length training short like the Vuori Kore Short covers most bases without excelling at any single one.
