Boasting two floors, three studios (including a heated one), and over 100 workouts per week, the flagship location of Fithouse off Union Square garnered the attention of over 500 new members in its opening weekend alone. Combined with the diversity of class types (barre, bounce, dance, HIIT, sculpt, and yoga) and instructors’ notoriously noteworthy energizing playlists, it’s the ultimate spot to sweat and be seen. Spread across 6,400 square feet, the one-stop shop also provides luxe showers, private changing areas, lockers equipped with charging stations, and a full refresh bar. Unlimited class memberships are $189/month.
