The Hard Candy Fitness Toronto club opened for business in October, joining international locations in Berlin, Rome, Sydney, Santiago, Mexico City, Moscow and St. Petersburg.
Classes were created by Madonna and are based on her daily workouts.
"She's definitely a big part of my life," said Marin, who regularly plays Madonna music in her classes and has seen the pop diva on tour.
"She has vision, she has discipline and she's fearless. Fearless. Absolutely fearless," she added, saying that the chance to dance with Madonna would be "insanely amazing."
