Madonna opens first gym
Madonna teaches dance class at "Hard Candy" gym chain launch
Madonna has opened the first branch of her Hard Candy gym chain in the upmarket area of Bosques de las Lomas in Mexico City.
To celebrate the launch of her new business venture, the star handpicked 20 lucky members and taught them a dance class to music by DJ Paul Oakenfold.
The Hard Candy gym membership in Mexico costs $160 a month, with a one off fee of $830, which includes two free months.
The gyms have been kitted out with state of the art machines and their walls are covered with pictures of the Material Girl.
