On this week's Fitness + Technology Podcast, Bryan welcomes veteran Australian fit-tech entrepreneur Deborah Goldberg to the podcast. Deborah came into the fitness industry ten years ago, with a focus of bringing Zumba to Australia, a nation with one of the world's worst obesity levels. Today, she works with AirFitness, designing tech products specifically for the fitness industry. She also launched Sub A Class, a free app that connects fitness instructors with one another to fill in or cover other instructor absences, as well as Morfis, an app that promotes business for fitness professionals.
