Les Mills, a New Zealand Olympian, former mayor of Auckland, and founder of the global Les Mills fitness brand, has died at age 91. Multiple outlets report that Mills competed for New Zealand at four Olympic Games between 1960 and 1972, including in discus and shot put. After his athletic career, he entered business and politics, serving three terms as Auckland mayor. The reports also say that he and his wife, Colleen, opened the first Les Mills gym in Auckland in 1968. Later, the family helped develop and spread structured group fitness programs that became internationally known, including BodyPump, which is associated with the brand worldwide. Statements attributed to family and brand representatives describe him as an influential figure across sport, business, politics, and public life. PR Newswire releases and local coverage characterize his death as peaceful and note his long-running role in building a fitness “dynasty” with his wife. Mills’ passing is widely reported as the end of a career that linked elite athletics, local leadership, and the development of a worldwide fitness industry.
