Men's gym shorts that actually keep up with your training — that's what this range is built around. From 5" inseam options that give you full freedom of movement to 7" cuts for a more relaxed fit, every pair is designed to handle the demands of the gym floor without getting in the way.
Whether you're lifting, running, or keeping it low-key on a rest day, there's a cut and construction here that fits the session. Men's sports shorts don't need to be complicated — they need to move with you, stay comfortable, and look sharp doing it.
Who This Collection Is For
This range is built for men who train with intent. If you're pushing heavy sets, grinding through intervals, or just want something that handles whatever the session demands, these men's workout shorts are made for that environment.
They're equally suited to guys who care about how their kit looks as much as how it performs. Clean colourways, versatile styles, and a fit that sits right whether you're in the gym or heading out after — this is training kit for men who don't want to compromise on either front.
When to Wear Men's Gym Shorts
These are built for the gym first — weight sessions, HIIT, circuits, cardio. The 5" inseam styles are cut for maximum mobility during compound lifts and explosive movements, while the 7" options offer a touch more coverage for box work, rowing, or anything that has you moving on a bench or machine.
The 2-in-1 styles with built-in liners are ideal for runs and high-output cardio where you want that extra layer of comfort without the bulk. Rest day styles carry the same comfort off the gym floor too — they're relaxed enough to wear around the house or out on a casual day without feeling like you're still in training gear.
Key Features
Multiple Inseam Lengths
The range spans 5" and 7" inseam options so you can choose the cut that suits your training style and personal preference. Shorter inseams give you the range of motion for squats and dynamic movements; longer lengths offer more coverage for varied training environments.
2-in-1 Construction
Several styles feature a built-in inner short that feels secure during high-intensity sessions without the need for a separate layer. The outer shell and inner work together to keep everything in place, letting you focus on the session rather than your kit.
Ventilation Built In
Mesh back yokes and side panels feature across key styles in the range, moving air through the fabric when your body temperature rises. It's a practical design detail that makes a real difference during longer or more intense workouts.
Secure, Adjustable Fits
Internal drawcords let you dial in the fit before you start training, so the waistband stays where it should throughout your session. Pocket detailing across multiple styles means you've got somewhere secure to stash your phone, keys, or earphones without adding bulk.

FAQs
What are the best men's gym shorts for weight training?
For lifting, a 5" inseam is the go-to — it keeps fabric out of the way during squats, deadlifts, and lunges without restricting your range of motion. The Men's Active Training Pocket Shorts in Black are a solid option here, with a 5" cut, mesh ventilation panels, and a secure fit that holds up through heavy sessions. If you prefer a bit more coverage, the 7" styles work just as well on the gym floor.
What's the difference between 2-in-1 shorts and regular gym shorts?
2-in-1 shorts have a built-in inner liner that moves with you and feels secure during high-output activity — think of it as a compression short stitched into the outer shell. Regular training shorts are a single layer, which some people prefer for a lighter, less structured feel. The Men's Hybrid 5" 2-in-1 Shorts are a good example of the format done well, with an inner short that adds comfort without adding bulk.
What are men's gym shorts made from?
Fabrics across the range are selected for performance — lightweight, quick-drying materials that stretch with your movement and don't weigh you down when you're working hard. Specific fabric compositions vary by style, so it's worth checking the individual product pages for the full breakdown on each pair.
How do I choose the right size?
Fit guidance and a full size chart are available on each product page. If you're between sizes, consider how you prefer your shorts to sit — snugger through the seat for 2-in-1 styles, or with a little more ease for sweat shorts and training styles. The adjustable drawcord waistbands across the range also give you room to customise the fit once you've found your size.
Are these shorts suitable for running as well as gym training?
Yes — several styles in the range cross over well between gym and run. The 2-in-1 options are particularly suited to running, since the built-in liner keeps everything in place over longer distances. The lightweight training shorts are another strong choice for cardio, thanks to their minimal construction and breathable fabrics.
How should I care for men's gym shorts?
Machine washing on a cool cycle is recommended for most styles — high heat can affect stretch fabrics and technical finishes over time. Avoid fabric softeners, which can clog moisture-wicking fibres, and tumble dry on a low setting or air dry where possible. Full care instructions are listed on each product label and product page.
Who designs the men's gym shorts at Myprotein?
Every style in the range is designed by Myprotein's in-house design team, who develop the cuts, fabrics, and features specifically around how men actually train. That means details like inseam length, ventilation placement, and pocket positioning are all considered from a performance-first perspective.
Can men's gym shorts be worn casually as well as in the gym?
Plenty of styles in the range work beyond the gym. The Rest Day Sweat Shorts are built with exactly that in mind — a relaxed cut and comfortable fabric that's just as suited to days off as active ones. Even the training-focused styles, with their clean colourways and tailored fits, hold up well outside of a gym environment.
