Gym King Returns to London with Westfield Pop-Up Shop.

We are returning to London this month with a pop-up retail experience at Westfield London, following a series of successful collection launches ahead of Summer 2026.

Running from 23rd May to 30th May, the pop-up will invite customers to experience the Gym King brand first-hand once again, building on the momentum and success of the brand’s first Soho pop-up store in 2025.

Customers can shop key pieces from Gym King’s latest and best-selling collections, bringing together men’s, women’s, and kids in one space. The pop-up has been designed to showcase the brand’s signature aesthetic across modern athleisure, elevated essentials, and performance-focused styles.

Customers will be able to experience the quality, fit, and detail of the collections first-hand within a premium retail environment that reflects the evolving direction of the brand.

More than just a shopping destination, the activation has been created as a fully immersive Gym King experience. Visitors can expect live DJs, food and drink, photobooth, and a free accessory for the first 100 customers.

The launch marks another significant step in Gym King’s wider retail strategy as the brand continues to strengthen its physical presence across key high-footfall locations.

Charlotte Hutton, Head of Brand at Gym King says:

“We’re looking forward to welcoming customers into our pop-up store at Westfield London this May and giving them the chance to experience Gym King in person.”

“It’s an opportunity to showcase the quality and detail behind the collections, from summer staples and everyday wear, to some of our best-selling gym pieces, whilst connecting directly with the community in one of the UK’s leading retail destinations.”
