As the days grow shorter and the temperature drops, maintaining workout motivation becomes a significant challenge for many across the UK. With New Year's resolutions on the horizon, the right activewear can provide the necessary boost to get you to the gym during the chilly winter months.
From Skin-Tight to Relaxed: The New Silhouettes
Frances Fountain, director of buying at Fabletics, confirms that while leggings remain a staple, fold-over, wide-leg workout pants are making a major impact. This flared silhouette offers a comfortable and flattering alternative to the compressive styles that have dominated for years, bringing a distinct noughties nostalgia to yoga and Pilates studios.
Tops are also undergoing a transformation, moving towards more avant-garde and feminine designs. Lightweight layering pieces are having a moment, according to Fountain, who highlights ruched cross-back designs and off-shoulder sweats as key trends. Figure-hugging tops with intricate straps or asymmetric necklines are elevating gym wear beyond basic attire.
Seasonal Colours and Cosy Textures
Burgundy has been dubbed the colour of the season and is now officially gym-approved. This deep, earthy tone is appearing everywhere on the high street and is perfect for winter workouts. Fountain also notes the popularity of other rich, festive shades like deep greens and warm reds, executed in a modern way.
In a surprising twist, cable-knit and bouclé-style knits are dominating gym wear layers, as seen in Kendall Jenner's viral Alo Yoga collaboration. The focus is firmly on winter comfort, with cosy fleece jumpers and soft sweats that remain stylish. The cropped-fleece silhouette, sitting neatly above high-waisted bottoms, is becoming the unofficial uniform for post-workout activities.
The Rise of Versatile Footwear
Versatility continues to lead the trends, particularly in footwear. Fountain emphasises that it's less about gym-only trainers this year and more about hybrid sneakers you can wear anywhere. This shift reflects the broader fashion trend of functional comfort becoming part of an everyday uniform.
Retro styles are making a strong comeback, with slimline trainers and the new 'sneakerina' gaining popularity. Fountain specifically mentions T90s and Speedcat ballet slippers as huge right now, representing a nod to the 2000s sports aesthetic. The key is finding footwear that transitions seamlessly from the treadmill to coffee runs, looking equally good with a trench coat as with activewear.
These trends, emerging in late November 2025, offer fresh inspiration for those seeking to maintain their fitness routines through the winter season with both style and comfort.
