About Men's Gym Clothes & Gymwear
The best approach when building a gym wardrobe is to start with what you actually do. Runners need different fabrics from lifters; outdoor training requires different weather-resistance from an indoor studio session. Sizes across men's gym clothes run from S to 6XL — one of the broadest ranges from any premium UK retailer. Free delivery on full-price orders over £50.
Which brands do OD's carry for men's gym wear?
The men's gym clothes range includes On Running, Reprimo, Red Run Activewear, Trailberg, BOSS, HUGO and more. On Running covers technical running and cross-training performance; Reprimo and Red Run Activewear focus on gym-specific training sets and compression styles; Trailberg covers outdoor-influenced activewear; BOSS and HUGO offer premium lifestyle gym styles.
What's the best gym kit for someone who does a mix of lifting and cardio?
For mixed training — weights and cardio in the same session — a four-way stretch short or jogger in a lightweight technical fabric is the most versatile base. Pair with a fitted performance tee with mesh ventilation panels. Avoid purely compression tights for lifting as restricted mobility can affect squat depth and deadlift form. On Running's training shorts and Reprimo's training sets are built for exactly this mixed-use scenario.
What sizes are available in men's gym clothes at OD's?
Men's gym clothes at OD's run from S to 6XL across most brands — one of the broadest size ranges available at the premium end of the UK activewear market. Performance brands like On Running use standard S/M/L/XL; BOSS and HUGO may also offer chest or waist measurements depending on the garment. Check individual product pages for current size availability.
How should I care for technical gym fabrics?
Technical fabrics used in gym wear — polyester, nylon, elastane blends — should be washed at 30°C or lower on a delicate cycle. Avoid fabric conditioner, which coats synthetic fibres and reduces their moisture-wicking performance over time. Tumble drying should be avoided; air-dry flat where possible to preserve stretch and shape. Turn garments inside out before washing to protect surface finishes and printed details.
