WELCOME TO

SerotoninClub

Opened in October 2025, Serotonin Club is a boutique fitness studio in Flatiron, NYC founded and run daily by two hands-on female founders and a small powerhouse team of women. Built to feel personal, welcoming, and community-driven, the studio offers innovative, results-focused classes including Pilates, sculpt, cardio, strength, pre/post natal classes, and more.


Our signature class, Serotonin Boost, blends Pilates and sculpt for a dynamic full-body workout designed to leave you feeling strong and energized. Beyond fitness, Serotonin Club is rooted in connection, hosting community events that bring people together both on and off the mat.
