Looking good in the gym doesn’t have to mean draining your bank account. Whether you’re lifting, running, or just trying to get through a spin class without feeling like your shorts are falling apart — there’s plenty of solid activewear out there that’s cheap, durable, and actually comfortable.
At BrokeButBuilt, we’ve rounded up 10 of the best activewear finds you can grab for £25 or less — so you can train hard and still afford your post-gym meal prep.
1. MyProtein Men’s Rest Day Shorts (£19.99)
Simple, breathable, and ideal for both workouts and casual wear. They’re often on sale, so keep an eye out for discount codes.
2. Decathlon Domyos Men’s Fitness T-Shirt (£7.99)
A lightweight, moisture-wicking tee that rivals brands double the price. Great fit and long-lasting material.

4. Primark Men’s Performance Tee (£6)
Primark’s activewear range is hit or miss — but their latest performance tees punch way above their price. Great stretch and surprisingly soft.
Available in-store only.
5. Gymshark Arrival Shorts (£24)
Sleek design, great movement range, and a reliable fit. Gymshark’s “Arrival” line is their best entry-level option.

6. Decathlon Men’s Training Tank Top (£9.99)
If you prefer a looser fit for upper-body days, this tank does the job well. Quick-dry and doesn’t cling mid-session.
7. BoohooMAN Active Quarter-Zip Top (£20)
Budget layering piece that looks premium. Good for outdoor runs or cool gym mornings.
8. ASOS 4505 Training Shorts (£18)
Solid value and decent quality — ASOS’s in-house activewear brand regularly drops big sales too.
➡️ asos.com
9. Amazon Essentials Men’s Quick-Dry T-Shirt 2-Pack (£16.99)
Nothing flashy, but perfect for everyday gym wear. Reliable fit, breathable fabric, and great for bulking up your rotation on the cheap.
➡️ amazon.co.uk
10. New Balance Cushioned Training Socks (3-Pack, £12.99)
Underrated essential — decent socks can genuinely improve comfort and reduce blisters during long sessions.
💡 BrokeButBuilt Tip:
Activewear doesn’t have to be top-brand to perform well. Focus on fit, fabric, and function — not the logo. Mixing one premium item (like shoes or a hoodie) with budget basics can look just as clean as a £200 outfit.
