Named after Miami's area code, ((305)) Fitness is a dance cardio workout with a live DJ. Classes infuse dance moves, sport drills and high-intensity interval training (HIIT) for a total body workout.

This dynamic workout was created by its Founder/CEO, Sadie Kurzban, who has been featured in NY Observer, Good Morning America, TODAY Show, TODAY with Kathie Lee + Hoda, Harper’s Bazaar, Style.com, New York Post, Fusion, and The Washington Post, for her uncanny ability to make a greuling workout feel like a party. Known as a 26-year old "ball of energy known for her sweat and smiling inducing workouts," she created her original workout method while attending Brown University. While there, she taught her revolutionary dance cardio workouts part-time as a student.

Kurzban placed first in the University's Entrepreneurship Competition, receiving $75K to launch ((305)) Fitness in NYC. With packed classes and also in beautifully branded studios in NY, Boston and Washington D.C., the "rave meets workout" is an underground non-stop cardio experience to create a full body workout. Classes feature a live DJ, and burn up to 800 calories in one session.

She still finds time to teach cardio and Sculpt classes, overseeing a staff of over 30 instructors and 20 DJs. In addition, she has traveled the country and beyond, from LA to Las Vegas to Chicago to Berlin, teaching ((305)) Fitness.

((305)) Fitness has two locations in NYC (West Village and Midtown), Washington, D.C., and Boston's Back Bay. Guests can enjoy full service locker rooms, showers and blow dryers. Soon, their apparel and boutique will be available as well.

Your workouts include the option between ((305)) Arms, ((305)) Legs and ((305)) Basics which is available at all locations. Recently, they launched Yoga 4 Better X and ((305)) Sculpt at their West Village location.
