Sustainable and ethical sportswear which has inclusive sizing, diverse imagery on site and in a range of fun bubblegum colours for each season? Hell yeah. It has an easy to navigate site with 2X – 4X with it’s own section. I’ve got my eye on some of the sculpting pieces for some long weekend getaways.

Most of Tala’s range also has pockets, zips or linings that are convenient and well thought out for your workouts. An all round well invested in adding those extra touches brand.

Goodmove is a high performance athleisure brand from Marks and Spencer. Everything from sweat-wicking fabrics to pure cotton pieces. It’s not just the regular fitness wear they have here, they also do waterproof jackets for those who like to work out in the wet weather too (probably good for dog walking too) and coming from M&S we all know the quality is great.

Simply Be in one of the UK’s leading plus size clothing brands, with sizes ranging up to a UK 32. They have a huge range of brands on site to also choose from including Under Armour, Adidas, Calvin Klein and Tommy Hilfiger.

Working out doesn’t need to be boring, leopard print matching sets for the gym? Yes please. Cue Shania Twain (or Rod Stewart) on the playlist. I’m also very into the long sleeve tops with thumb holes too – maybe it’s a comfort thing, but it makes me feel like I can take on the next workout class with ease.

RI-RI knows what she is doing with Savage X Fenty. Not only has she created an inclusive enterprise of empowering lingerie and loungewear, but also has created some very impressive activewear. Plus-size humans want access to next level pieces and she has created just that with her sportswear pieces. Sports bras with mesh details, glitter luxe cycling shorts with sexy cut-out details and sculpting one pieces that you can wear to yoga and even styled up and worn to the club.

Again, similar to Girlfriend Collection, there are so many versatile pieces that don’t just have to be worn in the gym.
