Current UK roundups consistently put Gymshark, Sweaty Betty, Adanola and TALA among the leading British names. Glamour's 2026 testing particularly highlights Gymshark for training, Adanola for minimalist activewear, TALA for style/sustainability and Sweaty Betty for premium performance. www.glamourmagazine.co.ukwww.vogue.co.uk

### My shortlist

1. Gymshark - best overall The safest choice if you're actually training rather than primarily buying athleisure. Particularly strong for lifting, gym sessions and seamless leggings. It originated in Birmingham and remains one of the biggest British activewear success stories. www.glamourmagazine.co.uk

2. Sweaty Betty - best premium I'd choose this for running, Pilates, yoga and versatile women's kit. Its Power leggings are particularly well regarded for support and durability. www.glamourmagazine.co.ukwww.vogue.co.uk

3. Adanola - best-looking Probably the winner if you want gym clothes that also work for coffee, travel and everyday wear. Its Ultimate leggings are currently around £40 and have an especially strong following. www.vogue.co.uk

### [Adanola Ultimate Leggings]() £40.00

4. TALA - best sustainable/style combination A good option if you want flattering, fashion-forward gymwear with an emphasis on recycled/natural materials. www.glamourmagazine.co.uk

5. Oner Active - best for sculpted gym sets Especially worth looking at if your priority is strength training and fitted/seamless sets.

### [ONER EnhanceLift Seamless Gym Leggings]() £58.00

6. BAM - best for eco-conscious basics More understated than Gymshark or Adanola, and particularly appealing for yoga, walking and lower-impact training. BAM is also highlighted among the UK's sustainable activewear options. flux.agency
