The Gym King is a British premium athleisure and activewear brand that blends fashion with fitness.
Founded in 2015 by former personal trainer James (Jay) Parker, the company started as a small "bedroom brand" before quickly growing into a multi-million-pound business. Based in the UK, Gym King offers a wide range of men's and women's apparel—including tracksuits, hoodies, leggings, and performance wear—designed to look good both inside and outside the gym.
The brand's philosophy is built around "lifestyle meets performance," with a strong focus on community, resilience, and an active mindset. Its rapid growth and popularity even led major retail giant JD Sports to acquire a stake in the company in 2021.
