 NEW ORLEANS, La. (DECEMBER 2, 2025) – HOTWORX®, the revolutionary 24-hour infrared fitness studio franchise, has officially reached another landmark moment with the opening of its 800th studio. In just eight years since its founding, the brand has grown from a single concept to a global phenomenon, reshaping how people approach health and wellness through efficient, science-backed infrared workouts.

“Reaching 800 studios is a moment that really makes us stop and appreciate how far this brand has come,” said Stephen Smith, Founder and CEO of HOTWORX. “This isn’t just about a number, it’s about hundreds of franchisees who believed in our concept and thousands of members who show up every day because they feel the difference infrared training makes. We’re proud of this milestone, and even more excited for what’s ahead.”

With additional international markets targeted for 2026 and beyond, the brand continues to build a powerful global footprint.
