Hard Candy Fitness was a chain of fitness centres that were a partnership between Madonna, her manager Guy Oseary and Mark Mastrov, the founder and CEO of 24 Hour Fitness. Founded in 2010, the venture had centres in Berlin (8 clubs), Mexico City, Moscow, Rome, Santiago, St. Petersburg, and Sydney. The company's name was a reference to Madonna's 2008 studio album Hard Candy. The German division went into administration in 2016 and closed its studios that year. That same year, the location in Toronto was rebranded as Aura Fitness after the initial media attention didn't translate into gym memberships. The only club remaining in operation as of 2019 was in Santiago, Chile, which rebranded as Energy Sport Club in May 2019.
