Winhoffer confirmed the news in a recent interview with The Huffington Post.

"In 2010 Madonna opened her first gym in Mexico City, and the idea for the opening was to teach a cardio class. She thought that would be a great idea, so we taught a class and the members loved it. She led the class and I was next to her," she explains. "I always document the programs I do with her, and we went through my diary and she chose one of the programs to turn into the DVD, which she named 'Addicted to Sweat.'"

According to Madonna's official website, the four-disc collection "showcases and teaches the Hard Candy Fitness' results-driven techniques and programming created by Madonna, which blends innovative dance, toning and cardio training." The entire set retails for $49.95.

Winhoffer insists that the queen of pop is the prime decision maker when it comes to her gyms and DVDs, picking both the music and the routine.

"Fitness is so important to her because she’s one to empower people. She is an example -- not just as a pop icon, but an example as a businesswoman, an entrepreneur, a woman that's in shape," she says. "The only way she is able to get through her day and schedule all her meetings and to be there for her children is to have a fit body. She makes time in her schedule for the workout. It gets her mind and body to connect. She always wants to be the best and everyone around her to be the best. Her fitness is the key. She's the perfect example to share her workout with people around the world."
