Les Mills, the New Zealand Olympian whose surname became synonymous with group fitness classes across the globe, has died at the age of 91. His passing marks the end of an era for an industry he helped revolutionise, blending choreographed exercise with community spirit in a format that now reaches millions in gyms from London to Lagos.
Mills represented New Zealand as a track and field athlete at the 1958 British Empire and Commonwealth Games, but his true legacy was forged in the years that followed. In 1968, he opened a small gym in Auckland, a venture that would eventually birth Les Mills International, the company behind BODYPUMP, RPM, and BODYCOMBAT. These programmes became the backbone of the modern fitness class, standardised yet adaptable, rigorous yet accessible.
The UK health sector, already grappling with rising inactivity and obesity rates, has particular reason to honour Mills. His formats are staples in British leisure centres and private clubs, used by councils and the NHS as part of public health initiatives. The company estimates that over 1.5 million people participate in Les Mills classes in the UK each week, a figure that underscores the brand's integration into the nation's wellness fabric.
Mills was not merely a businessman; he was a philosopher of movement. He understood that fitness had to be social to be sustainable. In an era where wearable tech and AI-driven coaching now dominate the conversation, his insight feels prescient. He argued that the "user experience" of exercise—the music, the instructor's energy, the sense of collective effort—mattered more than any metric. This human-centric approach is something our algorithm-obsessed age could learn from.
His death prompts a reflection on digital sovereignty in health. Les Mills’ content is now streamed via its app, a shift accelerated by the pandemic. This raises questions about data ownership and equity. While the company has been a leader in virtual fitness, the reliance on proprietary platforms creates dependencies. Mills himself, in his later years, voiced concerns about technology outpacing ethics, a sentiment that resonates with the current debates around AI in healthcare.
As we mourn Les Mills, we also honour a blueprint: fitness as a right, not a luxury. He democratised exercise, making it joyful and repeatable. His legacy will be measured not in market share, but in the heartbeats he quickened. The UK health sector, ever in need of affordable interventions, would do well to remember that the simplest algorithms are often the ones that move us most.
