All Bottoms

Shop Men's Gym Shorts & Training Bottoms

Whether you're lifting, running, or taking it easy on a rest day, the right bottoms make a difference. This collection covers the full range — men's gym shorts in 5" and 7" inseams, woven training shorts, lightweight options, 2-in-1 styles, and joggers built for both training and recovery.

Every piece is designed to move with you, not against you. With fabrics built for sweat, seam constructions that won't irritate, and fits that stay put through every rep and stride, there's a bottom here for every session on your schedule.

Who This Collection Is For

If you train regularly and want kit that keeps up, this range is built for you. From gym regulars who need durable, breathable shorts that handle heavy sessions, to runners looking for lightweight styles with a secure fit — the range spans enough variety to cover different training styles and preferences.

It's also for the guys who want options beyond just the gym floor. Rest day joggers and sweatshorts sit alongside performance training pieces, so whether you're doing a serious workout or keeping things low-key, there's something that fits the moment.

When to Wear Men's Training Bottoms

The shorter inseam styles — particularly the 5" and 7" options — are made for sessions where you need full range of motion. Think squats, deadlifts, sprints, and circuit training. Woven fabrics offer a looser, more breathable fit that suits high-intensity work and warm-weather training.

Joggers and sweatshorts come into their own on rest days, active commutes, or lower-intensity sessions like stretching and mobility work. The 2-in-1 shorts are a practical pick for outdoor runs, combining a liner with an outer for coverage and comfort without extra bulk.

Key Features

Inseam Options to Suit Every Preference

The range covers 5", 7", and 9" inseams, plus full-length joggers — so whether you want maximum freedom or a bit more coverage, there's a cut that suits your training style and personal preference.

Fabrics Built for Movement

Lightweight woven fabrics give a relaxed, airy feel during high-intensity sessions. Stretchy materials across the range move with you through lifts, lunges, and lateral steps without pulling or restricting.

Ventilation Where It Counts

Mesh panels and back yoke constructions feature across multiple styles, keeping airflow moving during tough sessions. It's the kind of detail that makes a noticeable difference when the training gets serious.

Secure, Adjustable Fits

Internal drawcords and elasticated waistbands feature throughout the collection, letting you dial in the fit before you train. Flatlock seam constructions on select styles reduce friction during movement — a practical touch for longer sessions.

FAQs

What are men's gym shorts?

Men's gym shorts are training-specific bottoms designed with performance fabrics, functional fits, and construction details that hold up during exercise. Unlike casual shorts, they're built around things like sweat-wicking materials, secure waistbands, and seam placements that won't chafe — details that matter once you're mid-session.

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

It comes down to your training and personal preference. The 5" inseam is a popular choice for gym work and lifting — it keeps things unrestricted and allows full range of motion through squats and lunges. The 7" length suits running and outdoor training where a bit more coverage is useful. If you prefer fuller coverage, the 9" option and jogger styles are worth a look.

Which men's gym shorts are best for running?

For running, the 2-in-1 styles are a strong choice — the built-in liner adds coverage and moves cleanly with you, while the outer layer keeps things looking clean. The Men's 5" 2-in-1 Training Shorts feature a reflective logo for low-light visibility and flatlock seams that minimise chafing over distance, making them a well-rounded pick for outdoor runs.

What's the difference between woven and standard training shorts?

Woven shorts are made from a non-stretch woven fabric that's typically lighter and more breathable than knit or jersey materials. They tend to have a looser, more relaxed drape — great for high-intensity sessions or warm conditions. Stretch-fabric shorts follow the body more closely and are a popular choice for lifting and gym floor work.

Are men's gym joggers suitable for training?

Absolutely. The training joggers and woven jogger styles in this range are built with performance in mind — think breathable fabrics, secure waistbands, and fits that don't restrict movement. They're equally at home during a warm-up, a light session, or a rest day walk. If you run cold or train in a cooler environment, joggers are a practical alternative to shorts.

How should men's training shorts fit?

Training shorts should feel secure at the waist without digging in, and give you full freedom of movement through the hips and thighs. Use the size guide on each product page as your starting point — and pay attention to the inseam length, as that'll have the biggest impact on how a style feels during different types of exercise.

How do I care for men's gym shorts and joggers?

Check the care label on each garment for specific guidance, as fabric composition varies across the range. As a general rule, machine wash on a cool setting, avoid fabric softeners (which can affect moisture-wicking properties over time), and air dry where possible to keep the fabric performing at its best.

Who designs the men's training bottoms at Myprotein?

The full collection is designed by Myprotein's in-house design team. Each style is developed with real training demands in mind — from the choice of fabric and construction details through to fit and functionality across different workout types.
