Madonna is set to open a chain of gyms that unite fitness and entertainment, it's been announced.

The Hard Candy Fitness Centres, which share the same name as the singer's 2008 album, will offer kick-boxing and yoga programs.

The venture brings together Madonna and 24 Hour Fitness founder Mark Mastrov, as well as the singer's manager Guy Oseary, reports The Telegraph.

"Madonna's touch will be everywhere," Mr Mastrov said.

The first gym is due to open in Mexico City next month, with additional outlets outlined for Europe and Asia.
