1. Wide-Leg Leggings Revolution
This summer, comfort truly reigns supreme, and honestly, we’re here for it. The wide-leg activewear legging has emerged as the undisputed queen of relaxed chic. They’re a total game-changer if you’re tired of feeling squeezed!
Their appeal? Incredible versatility! These aren’t just for a gentle yoga session. Oh no. They transition effortlessly from your morning meditation to a leisurely park stroll, or even a casual work-from-home setup. Plus, the breathable fabric and roomy fit ensure you stay cool and comfortable, no matter how high the temperatures climb.
To nail this look, try pairing your wide-leg leggings with a more fitted crop top or a sleek sports bra. It balances the voluminous bottom half perfectly. Or, throw on an oversized hoodie for that ultimate relaxed vibe. Brands like Next have nailed this trend. Check out their wide-leg leggings for the most comfortable workoutwear.
2. Scrunch Bum Leggings & Sculpting Fits
Prepare to see more “glute-sculpting” magic this summer – and yes, it’s entirely intentional. Fuelled by viral TikToks (we’ve all seen them!) and a growing focus on lower body strength, scrunch bum leggings and other sculpting fits are seriously dominating activewear collections. And let us tell you, these aren’t just about looking good; they’re engineered to make you feel incredible.
The genius of this trend lies in its clever design. We’re talking strategically placed seams, ruched detailing, and those magical compression fabrics. The result is a silhouette that genuinely enhances your natural curves. It makes you feel so much more confident and supported, whether you’re hitting a heavy squat session or just feeling your best while running errands. It’s about owning your power, plain and simple.
The scrunch bum leggings are a prime example of where performance meets utterly flattering design. The advanced fabric blend offers comfortable compression and flexibility, ensuring you can move without restriction while feeling perfectly sculpted. Leading the charge in this space are brands like Invested Athlete and their must have scrunch bum leggings.
3. Butter Yellow & Pastel Palettes
Say goodbye to gloomy workout gear! Summer 2025’s activewear palette is bursting with bright colours and soft tones. We’re seeing butter yellow, gentle blush pinks, and serene baby blues everywhere. They’re gracing gym floors, yoga studios, and morning running routes right across the UK. It’s such a refreshing change that genuinely adds joy to your routine.
These pastels offer a sophisticated yet playful way to inject colour into your active wardrobe. Unlike those intense neons, they’re softer, way more wearable, and incredibly versatile. They truly evoke a sense of calm and brightness. Perfect for those sunny outdoor sessions or simply uplifting your mood during an indoor workout.
Thinking of how to wear them? Try a full pastel co-ord for a high-impact, chic look. Or, simply integrate a butter yellow sports bra or a blush pink oversized tee into your existing neutrals. UK brands like Sweaty Betty are totally embracing this trend. Just check out Instagram; you’ll see these gorgeous hues styled everywhere, proving just how fresh and uplifting they really are.
4. Unitards & One-Piece Workout Sets
The one-piece wonder is officially back! And honestly, it’s chicer and more wearable than ever. Unitards and seamless one-piece workout sets are having a major moment. Effortless style can also be incredibly functional, which, let’s be real, is a total game-changer for those busy mornings.
They’re incredibly appealing for exercises like yoga, barre, pilates and dance thanks to the flexibility they provide. They also provide a sleek, streamlined silhouette and offer unparalleled freedom of movement. Plus, the flattering fit means you’ll feel supported and confident throughout your session.
Styling them is simple: add a pair of fresh trainers for a cohesive look. Or, throw an oversized t-shirt or a cropped hoodie over the top for a cool, post-workout vibe. Brands like Fabletics offer a wide array of stylish unitards, from full-length options to shorter jumpsuits.
5. Capri Leggings Comeback
The capri legging has firmly re-established itself as a summer activewear staple. Their resurgence is actually super logical, especially when you think about the British summer. They offer the perfect balance: the coverage and support of a full-length legging, but with added breathability around the ankle and calf. This makes them absolutely perfect for those unexpected heatwaves, outdoor park workouts, or simply running errands when full-length feels just too heavy. They’re the ideal compromise for comfort when the sun is blazing.
The key to rocking the 2025 capri? Look for modern cuts and performance fabrics. Definitely pair them with a statement sports bra or an oversized top, and complete the look with chunky trainers for a contemporary edge. The Sculpting Capri Leggings from Next is a classic style that’s both functional and fashion-forward.

Activewear this summer is all about celebrating comfort and that effortlessly cool vibe! It’s perfectly epitomised by the pairing of oversized slogan tees and relaxed layers with more fitted bottoms. It’s a look that just screams effortless cool.
This trend strikes the perfect balance. The oversized top provides all the comfort and freedom you could want. But by pairing it with sleek shorts or leggings, you maintain a sense of shape and athleticism. It’s ideal for warming up, cooling down, or just creating a relaxed yet stylish active look that works for your coffee run as much as your gym session.
