Les Mills, the Olympian and fitness entrepreneur who built one of the most widely recognised exercise brands in the world, has died at the age of 91, according to a report by BBC News.
A Legacy in Group Fitness
Mills founded Les Mills International, a company that grew into a global presence in the fitness industry. The brand became particularly associated with choreographed group workout programmes set to music — a format that distinguished it within the broader landscape of gym-based exercise.
Among the programmes most closely linked to the brand are Body Pump and Body Combat, both of which became fixtures in fitness facilities around the world. The company's model of pairing structured movement with music helped define what large-scale group exercise looked like for millions of participants across multiple decades.
From Athletics to Enterprise
Before establishing his fitness enterprise, Mills competed as an Olympian — a background that informed the performance-oriented ethos the brand would later project. The combination of elite athletic experience and commercial vision placed him in a relatively rare category of sports figures who successfully translated competitive credentials into lasting industry influence.
BBC News reported his death without specifying the cause. He was 91.
The Brand He Left Behind
Les Mills International has expanded considerably since its founding, with its choreographed programmes now offered across a wide range of gym and fitness centre environments internationally. The company's identity has remained closely tied to the group workout format that Mills helped popularise — one in which music, movement, and collective participation are central elements.
The fitness sector has changed substantially over the course of Mills's career, with the rise of digital platforms, on-demand exercise content, and home-based workouts reshaping how people engage with structured physical activity. Les Mills International adapted to a number of those shifts, extending its reach beyond physical gym spaces.
His death marks the end of a career that spanned elite sport and commercial enterprise, leaving behind a brand whose programmes continue to be delivered in fitness facilities across the globe.
