Les Mills, the New Zealand-born fitness revolutionary whose name became synonymous with group exercise, has passed away at the age of 91. His death marks the end of an era for the global fitness industry, a sector he single-handedly democratised through choreographed workouts set to thumping music. In a fitting tribute, British gym chains have announced plans to adopt the ‘Les Mills Method’ as a permanent fixture in their schedules, cementing his legacy for a new generation.
Mills was not merely a businessman; he was a philosopher of movement. Born in 1934, he represented New Zealand in weightlifting and track and field at the 1950s Empire Games before becoming a physical education teacher. In 1968, he founded Les Mills International, but it was his son Phillip who transformed the brand into a global phenomenon with the creation of BodyPump, BodyAttack, and RPM. Yet Les remained the spiritual core: a man who believed fitness was a right, not a luxury.
His method, which combines music, motivation, and measurable results, turned exercise into a communal experience. It was a precursor to the quantified self movement, decades before Fitbits and pelotons. Every squat, lunge, and push-up was timed, every beat counted. This was analogue precision in a digital age.
The tributes have been swift. David Lloyd Leisure, PureGym, and Nuffield Health have all pledged to rename their group exercise studios ‘Les Mills Spaces’ for a week. More profoundly, they will embed his teaching philosophy: instructors are trained not just to lead but to inspire, to watch for the person at the back who is struggling, to adjust and encourage. That human touch, increasingly rare in an age of algorithm-driven personalisation, is his true inheritance.
Yet there is a darker footnote to this story, one that reflects my own anxieties about our technological trajectory. Les Mills’ success relied on physical gatherings, shared sweat, and real-time human feedback. Today, the company has diversified into digital platforms, with on-demand classes and virtual reality workouts. The pandemic accelerated this shift, and the Les Mills app now beams workouts into millions of homes. But what is lost when a mentor becomes an algorithm? The company’s use of AI to analyse form via webcams is clever, but it cannot replace a trainer’s intuition. We risk turning fitness into a solitary, screen-mediated activity, stripping it of the community that Les Mills championed.
This tension between human connection and digital efficiency is the central challenge of our era. Les Mills understood that motivation is contagious, that a room full of people moving together creates a collective energy no gadget can replicate. His death should prompt us to question not just how we exercise, but why. Are we building gyms or data centres? Are our wearables liberating us or locking us into performance metrics that ignore joy?
The British gym chains’ tribute is a start, but it must be more than symbolic. If they truly honour his method, they will double down on the human element: hiring more instructors, reducing class sizes, investing in training that emphasises emotional intelligence over technical certification. The technology is a tool, not the teacher.
Les Mills often said, “The greatest enemy of a good plan is the dream of a perfect plan.” In our quest for the perfect workout, powered by AI and quantified data, we must remember that fitness is fundamentally human. It is about feeling alive, not just living longer. As the news spreads, I hope the industry reflects on that wisdom. The method lives, but the man is irreplaceable.
An era ends, and a test begins: will we use our new tools to amplify connection or replace it? The Les Mills Method, at its core, is a reminder that the best interface is still a smile, a shout of encouragement, a hand on a shoulder. That is something no algorithm can hack.
