If you train hard and want bottoms that keep up, this range is built for you. Lifters, runners, HIIT devotees, and anyone who hates being restricted by stiff, sweaty fabric will find something that works in here.

When to Wear Men's Training Shorts and Bottoms
Men's sports shorts and training bottoms in this collection are designed to cover the full range of what you do. Shorter inseams and mesh panels suit high-intensity gym work and cardio where you want airflow and unrestricted movement. Woven fabrics and 2-in-1 constructions are built for functional training, where range of motion matters most.
Joggers and sweatshorts earn their place on rest days, warm-up laps, and cooler outdoor sessions. The lightweight options cross over easily into everyday wear — structured enough to look sharp, comfortable enough to actually live in.
Key Features
Built-In Ventilation
Mesh back yokes, side panels, and perforated zones are positioned to move air during the moments you generate the most heat. You stay cooler without sacrificing coverage or structure.
4-Way Stretch Fabrics
Woven and jersey fabrics across this range are engineered to stretch in every direction. Deep squats, lateral lunges, and explosive movements all feel unrestricted — the fabric moves with you rather than against you.
Secure, Customisable Fit
Internal drawcords and elasticated waistbands let you dial in the fit for your build and your session. Nothing shifts, rides up, or loosens mid-rep.
Versatile Lengths and Styles
With 5" and 7" inseam options across men's athletic shorts, plus jogger and sweatshort styles, there's a cut for every preference and every environment — gym floor, outdoor track, or the couch between sessions.

FAQs
What are the best men's gym shorts for training?
It depends on what you're doing. For heavy lifting and gym work, a 5" inseam short with mesh ventilation — like the MP Men's Active Training Pocket Shorts — gives you the airflow and leg freedom to move without restriction. For mixed training or if you want a bit more coverage, a 7" 2-in-1 style with a jersey inner layer adds confidence during dynamic movements without feeling bulky.
What's the difference between 5" and 7" training shorts?
The inseam length changes how the short sits and feels in motion. A 5" inseam sits higher on the thigh, offering maximum range of motion — popular for lifting, sprints, and anything that demands full leg freedom. A 7" inseam provides more coverage and is a common choice for longer runs or if you simply prefer a slightly more modest cut. Both lengths appear across this range in woven and stretch fabrics.
Are men's sports shorts suitable for running as well as the gym?
Yes — several styles in this collection work across both. Lightweight woven shorts with internal drawcords are built to stay secure during runs, while mesh panelling keeps things cool under sustained cardio effort. The 2-in-1 shorts, with their inner jersey layer, are particularly well suited to outdoor running where extra coverage is welcome.
How should men's workout shorts fit?
Training shorts should sit comfortably at the waist without needing constant adjustment — the internal drawcord is there to help you lock that in. Around the thigh, you want enough room to squat and lunge freely without excess fabric getting in the way. If you're between sizes, sizing up typically gives more comfort during dynamic movements, while sizing down offers a closer, more streamlined feel.
How do I care for training shorts and joggers?
Machine wash on a cool or gentle cycle and avoid tumble drying where possible — heat can break down stretch fabrics over time. Turn garments inside out before washing to protect any prints or panels, and skip fabric softener, which can clog moisture-wicking fibres and reduce their effectiveness.
What materials are used in these training bottoms?
The range uses a mix of woven polyester, stretch jersey blends, and lightweight fabrications depending on the style. Woven fabrics offer structure and durability with good stretch, while jersey-based options and sweatshort fabrics lean into comfort and softness. Specific fabric compositions are listed on each individual product page.
Who designed these products?
Every piece in this collection was designed by Myprotein's in-house design team. Each style is developed with real training in mind — balancing performance construction, practical features like pockets and drawcords, and clean aesthetics that work as well outside the gym as they do in it.
Can I wear these men's athletic shorts for activities other than the gym?
Absolutely. The sweatshorts and joggers in particular are built with a dual-purpose mindset — structured enough to wear out, relaxed enough to recover in. Even the training shorts cross over well into casual wear, especially the clean, minimal colourways like black, navy, and storm grey available across the range.
