Sadie Kurzban, 30-year old founder and CEO of 305 Fitness, began working on 305 as a side hustle her senior year of college at Brown University. 305's emphasis on inclusivity and body-positivity was a direct response to Kurzban's battle with disordered eating growing up in Miami. On social media, she utilizes her personal account to share more than dance moves. Dubbed “the next fitness cult leader” by the New York Observer, Kurzban is a bold, outspoken leader of the next generation. 305 Fitness currently has 7 locations in New York, Washington D.C., and Boston, with weekly pop-up experiences in Los Angeles, San Francisco and Chicago and pushing 1000 certified instructors teaching their method across the globe
