Men's gym shorts are one of those kit essentials that can make or break a session. Get them right and you barely notice them — they move when you move, stay where they should, and don't slow you down. The men's shorts collection covers everything from 5" training cuts to longer 7" and 9" inseams, with styles built for the gym floor, outdoor runs, and recovery days in equal measure.

Whether you're after men's athletic shorts with a built-in liner for added coverage, lightweight woven styles for unrestricted movement, or relaxed sweatshorts for off-day comfort, there's a fit here for every training style and preference.

Who This Collection Is For

These men's sports shorts are built for anyone who trains seriously and wants their kit to keep up. If you're lifting, running, doing circuits, or mixing it up across different sessions, you'll find a cut and fabric that suits the way you move. The range spans structured fits with compression-feel liners and breezy woven styles that let you go hard without overheating.

It's also a solid pick for anyone who wants versatility — shorts that work in the gym but don't look out of place on a rest day walk or a casual weekend. With multiple inseam lengths and colourways ranging from core blacks and navies to deeper seasonal tones, there's something here whether your priority is performance or everyday wear.

When to Wear Training Shorts

Men's workout shorts from this range are designed to handle a wide variety of sessions. The woven styles with 4-way stretch are a natural fit for weightlifting, HIIT, and functional training — anywhere you need full range of motion without fabric pulling or restricting. The 2-in-1 designs are particularly well-suited to outdoor training and running, where the inner jersey layer keeps things comfortable and secure as you move.

On the lighter end, the lightweight training shorts work well for cardio sessions, warm-weather runs, or any workout where staying cool is the priority. And when you're not training? The rest day sweatshorts are exactly what they sound like — made for switching off, not just warming up.

Key Features

Multiple Inseam Options

The collection comes in 5", 7", and 9" inseam lengths, so you can choose the cut that suits your preference and training style. Shorter inseams give more freedom of movement for dynamic workouts, while longer cuts suit those who prefer a bit more coverage during lower-body sessions or outdoor activities.

4-Way Stretch Woven Fabric

Several styles use a 4-way stretch woven construction that flexes in every direction without losing its shape. It's a fabric that feels structured enough to look clean but flexible enough to handle squats, lunges, and everything in between.

2-in-1 Built-In Liner

A number of shorts in the range feature an inner jersey layer that sits close to the body, giving a secure, confident feel during higher-intensity sessions. No extra layers needed — the liner is already built in and stays comfortable throughout your workout.

Secure, Adjustable Waistbands

Internal drawcords run through most styles in the collection, letting you dial in the fit before you start. Whether you're mid-session or on the move, the waistband stays put without digging in or shifting around.

FAQs

What length of men's gym shorts should I choose?

It comes down to the type of training you do and personal preference. The 5" inseam sits higher on the thigh and gives maximum freedom of movement — popular for running and fast-paced gym sessions. The 7" is a versatile middle ground that works well for lifting and general training. The 9" option offers more coverage and is a solid pick for outdoor workouts or if you simply prefer a longer cut. All lengths are available across multiple styles in the collection.

What's the difference between 2-in-1 shorts and standard training shorts?

2-in-1 shorts have a built-in inner jersey layer that sits close to the body underneath the outer shell. This gives you a more secure, supportive feel without needing to wear separate compression shorts underneath. Standard woven training shorts have a clean, single-layer construction that's lighter and more breathable — better if you run warm or prefer a less fitted feel. Both styles use stretch fabrics designed to move with you through a full range of motion.

Which men's shorts would you recommend for running?

The MP Men's 2-in-1 7" Training Shorts are a strong option for running. The inner jersey layer keeps everything in place as you move, and the 4-way stretch woven outer shell moves freely without bunching or dragging. If you want a slightly shorter, more compact fit, the MP Men's Hybrid 5" 2-in-1 Shorts are worth a look — the built-in inner shorts add comfort over longer distances, and the internal drawcord keeps the waistband exactly where you want it.

How do I find the right size?

Myprotein's size guide is the best place to start — it lists waist and hip measurements against each size so you can check before you order. Most styles in the collection are designed with an athletic fit in mind, meaning they're tailored through the waist and seat without being restrictive. If you're between sizes, the adjustable internal drawcords on most styles let you fine-tune the fit at the waist.

How should I wash my training shorts?

Most shorts in the range are machine washable — check the care label on your specific style for the recommended temperature. As a general rule, washing inside out at a low temperature helps preserve the fabric's stretch and colour. Avoid fabric softeners, which can break down performance fabrics over time, and skip the tumble dryer where possible to keep the fit consistent wash after wash.

Who designs the Myprotein men's shorts range?

All styles are designed by Myprotein's in-house design team. They develop each piece with performance and practicality in mind — testing fabrics, fits, and construction to make sure the end result holds up during real training sessions, not just on paper.

Are these shorts suitable for both gym and casual wear?

Several styles in the range cross over comfortably between training and off-duty wear. The woven training shorts and lightweight styles have a clean, minimal look that works outside the gym, while the rest day sweatshorts are specifically designed for exactly that — relaxed fit, soft fabric, and a more casual silhouette. The men's athletic shorts in core colourways like black, navy, and grey marl are particularly easy to wear beyond the gym.

What materials are used in the men's shorts collection?

The collection uses a range of performance fabrics depending on the style. Woven training shorts typically use a stretch woven construction with 4-way stretch for mobility. Lightweight styles use lighter, more breathable fabrics suited to high-output or warm-weather sessions. 2-in-1 shorts combine an outer woven shell with an inner jersey liner. Rest day sweatshorts use a softer, fleece-feel fabric for comfort off the gym floor. Specific fabric compositions are listed on each product page.
