The Barre Code has expanded from a small studio space to a national franchise which includes multiple locations throughout the U.S. Workouts center around the ballet barre and feature stamina-building exercises that help rapidly build stronger arms, abs, thighs, and glutes. New routines are available each week and classes that include kickboxing, high-intensity interval training, yoga, and dance continually evolve to keep up with fitness innovations. Participants can also count on instructors to regularly introduce new props and moves to keep them interested and seeing results. The expansive studio gives practitioners plenty of space to swish their limbs to inspiring music and vintage dishwashing-detergent jingles.
