Les Mills, the four-time Olympian and founder of the global fitness brand Les Mills International, has died at 91. His empire, built on the choreographed group workout classes that now command a cult following in over 100 countries, leaves a mark on how Britain exercises. Mills was a New Zealander, yes, but the wellness revolution he championed has deep British roots. His story is one of a mid-century fitness boom that started in British gymnasiums, crossed the Empire, and came back stronger.
Mills first made his name on the track. He represented New Zealand in the 1950s and 1960s, competing in the discus and shot put at four Olympic Games. No medals. But that was never the point. His real legacy began when he inherited his father’s gym in Auckland in 1968. The family business, Les Mills Gym, became a hub for a new kind of physical culture. It was there that his son Phillip, now CEO, started experimenting with music-led, instructor-led classes. The result: BodyPump, the barbell class that launched in 1991 and changed fitness forever.
The timing was perfect. Britain, the birthplace of the modern gym movement, was ripe for a revolution. The British love of routine and ritual found its match in Les Mills’ structured releases of new choreography every quarter. Gym chains like David Lloyd and Fitness First snapped up the licences. Today, Les Mills classes are a fixture in British leisure centres, from Chelsea to Carlisle. The brand’s success is a quiet victory for British-style fitness: organised, communal, and slightly obsessive.
Mills himself was a figure of modest charisma. He never sought the spotlight. His focus was on the product, the science, the music. He was a former physical education teacher who believed in the power of group dynamics. That belief made him a billionaire, on paper, but he lived modestly. Friends recall a man who still taught classes into his 80s, barking instructions in a voice that carried the authority of a man who had done it all.
The political angles are harder to spot, but they are there. Mills tapped into a neoliberal wellness economy that prizes individual self-improvement. Labour or Tory, every government has pushed public health messages about exercise. Les Mills gave them a tool. The brand worked with the NHS on pilot schemes for obesity and mental health. It is a rare example of private enterprise delivering public good without a fuss.
Tributes have poured in. Downing Street issued a statement praising his “extraordinary contribution to the nation’s fitness”. That is code for: we know how many Britons use his classes, and we are grateful. The fitness industry is a multibillion-pound sector, and Les Mills sits at its heart. His death marks the end of an era, but the classes will march on. The quarterly releases are already planned for 2025. The music will keep playing.
In Westminster, few will mark his passing with a tribute. That is fine. Les Mills was never a man for the corridors of power. He was a man for the gym floor. And on that floor, thousands of Britons will pause this week to remember him. They will lift a barbell, or strike a pose, and think of the old Olympian who showed them how to feel strong. That is a legacy worth more than any vote.
