The Best UK Black Friday Deals for Activewear in 2025

Black Friday 2025 has arrived with some of the strongest activewear discounts UK shoppers have seen in years, making it an ideal moment to refresh fitness wardrobes affordably.

South Asians across the UK are increasingly choosing high-quality activewear that supports running, gym sessions and wellness routines without stretching budgets.

This year’s deals feel particularly impressive because leading brands are dropping prices across their most popular leggings, trainers, sports bras and matching sets.

Gymshark, Nike, Adidas, Puma, JD Sports, Sports Direct and Under Armour are all offering major reductions, with many items falling by 50 to 60 per cent.

Several products even exceed those headline numbers, especially limited colourways and seasonal drops that retailers are clearing quickly.

With so many offers to consider, shoppers are encouraged to compare prices early and secure their favourites before sizes disappear.

Gymshark Leads With Deep Sitewide Savings

Gymshark’s Black Friday 2025 sale continues to dominate the UK activewear space thanks to generous reductions across men’s and women’s collections.

Shoppers can expect up to 50 per cent off everything sitewide, which is unusual because the brand rarely launches such broad discounts.

Many favourites, including leggings, shorts, hoodies and sports bras, are marked down even further with reductions close to 70 per cent on selected pieces.

These deeper cuts are already attracting strong demand, and popular sizes are selling through at a rapid pace.

Both online and in-store shoppers are finding that certain colours disappear first, particularly neutral tones and core black styles.

With UK fitness enthusiasts stocking up early, those wanting complete matching sets are advised to check quickly before items are gone.

Nike Offers Thousands of Discounted Styles

Nike’s Black Friday event has returned with one of its largest ranges of reduced products available to all shoppers this year.

The brand is offering up to 50 per cent off thousands of styles, including running gear, lifestyle favourites and high-performance training essentials.

This wide variety appeals to South Asians who want versatile pieces that transition from workouts to casual daily wear.

Many shoppers are focusing on discounted leggings and supportive sports bras because these staple items are rarely reduced so significantly.

Trainers are also performing strongly in sales, particularly running silhouettes that feature cushioning suited for longer mileage.

With stock moving quickly, browsing early is the best way to secure favourite pieces before they sell out in limited sizes.

Adidas Delivers Strong Reductions on Performance Wear

Adidas has embraced Black Friday 2025 with generous discounts across performance clothing, trainers and accessories.

The brand is offering up to 50 per cent off many categories, giving shoppers plenty of chances to secure durable activewear for long-term use.

Popular running models such as Adizero silhouettes are cut by around 40 per cent, which makes them a standout option for fitness lovers prioritising speed or support.

Other trainer styles sit between 25 and 30 per cent off, which provides room for shoppers to explore newer designs at more manageable price points.

South Asians looking for stylish pieces that blend sport and streetwear will appreciate the reduced tracksuits and casual fits.

With strong demand for Adidas this year, particularly in trendy colourways, early browsing remains important for securing the best items.

JD Sports and Sports Direct Give Multibrand Flexibility

JD Sports continues to be a favourite for shoppers who want to mix brands in one purchase, while using discounts like student savings or BNPL when helpful.

Their Black Friday section shows many trainers and sportswear essentials between 20 and 50 per cent off, spanning Nike, Adidas, Puma and other sought-after labels.

This variety helps shoppers compare fits and price points without jumping between different websites.

Sports Direct is another strong option, especially for those wanting budget-friendly basics for gym sessions or training routines.

Its Black Friday event covers men’s, women’s and kids’ activewear, making it useful for families preparing for winter fitness habits.

With both retailers offering broad ranges, shoppers can conveniently upgrade wardrobes while sticking to budget goals.

Puma and Under Armour Highlight High Discount Picks

Puma’s Black Friday and Cyber Monday offers have drawn interest from women seeking affordable high-waist leggings and supportive training tights.

Selected products are discounted by up to 60 per cent, making the brand highly competitive for anyone wanting stylish athleticwear on a budget.

Puma has also reduced many running shoes, which benefits shoppers looking for comfortable pairs suited to gym classes and outdoor sessions.

Under Armour is also standing out with up to 50 per cent off performance clothing, trainers and accessories.

First-time email subscribers can access an additional 15 per cent off, allowing new shoppers to stack savings effectively.

These reductions make both brands ideal for South Asians wanting technical fabrics without premium price points.

Black Friday 2025 delivers a wide selection of activewear deals across leading UK brands, giving South Asian shoppers countless opportunities to update their fitness wardrobes.

Gymshark, Nike and Adidas remain the biggest highlights thanks to deep cuts across their most popular collections.

Multibrand retailers like JD Sports and Sports Direct offer added convenience for anyone wanting to compare brands without overspending.

Puma and Under Armour provide some of the highest discount percentages, particularly for tights, trainers and performance clothing.

With so many offers available, browsing early helps secure the best fits, sizes and colourways.
