Beginning in 2001 as a small fitness studio in the basement of an office building, Pure Barre has since blossomed into a widely acclaimed, widely publicized approach to exercise with a nationwide following. Dancer, choreographer and fitness buff Carrie Rezabek Dorr founded Pure Barre more than a decade ago in Birmingham, Michigan. The Pure Barre technique can be a fast and effective way to transform your body—pushing muscles to their limit. Motivating music slices through the 50-minute high-intensity but low-impact workouts, each of which utilizes a ballet barre and small isometric movements designed to burn fat and create long, lean muscles.
