Tone House really is the hardest workout in New York City. Boasting experience in dance and fitness, Callie knows how to challenge you to compete with yourself. Take her class and you'll train like the elite athlete we all aspire to be. Her CORE class will have you crying when you laugh for the rest of the week, but it's so worth it. Sign up for Callie's class here!
