The fitness world has lost a titan. Les Mills, the New Zealand-born Olympic runner who became one of the most influential figures in global exercise culture, has died at the age of 91. To most of us, Les Mills is the name on the gym timetable: BodyPump, RPM, BodyCombat. But the brand that turned group fitness into a multi-billion dollar industry was built on the bones of a life devoted to pushing physical limits. And in a quiet way, his death marks the end of an era for how Britain exercises.
The news of his passing, confirmed by the Les Mills International company, has prompted tributes from athletes and celebrities who credit his programmes with their strength and stamina. But beyond the testimonials, there is a deeper cultural shift to consider. The Les Mills phenomenon didn't just sell workout videos. It sold a philosophy: that exercise could be a shared, almost spiritual experience, choreographed to a soundtrack and led by a charismatic instructor. Before Les Mills, the gym was a solitary grind. After Les Mills, it became a dance floor.
Born in 1930 in the small town of Whakatane, New Zealand, Mills was a middling runner by international standards. He competed in the 1954 Commonwealth Games and the 1958 British Empire and Commonwealth Games, but never medalled. Yet his true legacy lies in what he built with his son Phillip. In 1997, they turned the family's Auckland gym into a laboratory for a new kind of fitness: classes that were replicable, scalable, and wildly addictive. The first BodyPump class, with its barbell and repetition counts, changed the way people thought about strength training. It made weightlifting accessible to the masses.
Why does this matter to the British reader? Because Britain, perhaps more than any other country, embraced the Les Mills model. Our high streets are lined with gyms that run Les Mills classes on loop. It has become a staple of middle-class life: the 6am BodyPump session before the school run, the lunchtime BodyAttack for office workers. Mills himself was a regular visitor to the UK, and his programmes have been adopted by organisations from the NHS to the British Army. In 2019, a study found that nearly 1 in 10 British adults had taken a Les Mills class.
But there is a human cost to consider. The rise of branded fitness has driven up the cost of exercise. A single Les Mills class can cost £10 a session, and the monthly membership at a gym that offers them can be double that of a basic gym. For those on lower incomes, the price of participation has become prohibitive. Mills's empire, for all its good intentions, has contributed to a two-tier fitness system: those who can afford the choreographed experience, and those who cannot. The latter are left with the free weights and the old sense of isolation.
Yet it would be churlish to focus on the negatives on a day of mourning. Mills's impact was overwhelmingly positive. He made exercise fun. He gave millions of people, especially women, a safe space to push their bodies. His classes were a release from the pressures of modern life, a place where you didn't have to think, just feel the beat. That, perhaps, is his greatest legacy: not the business empire, but the joy he injected into the mundane business of staying healthy.
As the tributes pour in, we should remember that Les Mills was not a body builder or a Olympic champion. He was an ordinary athlete who saw a way to make extraordinary changes to ordinary lives. He understood that fitness was not about medals. It was about morale. And in a country like Britain, where the weather is grey and the news is often grim, that morale boost has been worth its weight in gold.
Rest in peace, Les Mills. You made us stronger, but more importantly, you made us happy.
