### 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
