From Internment Camp to $120 Billion Industry

Joseph Pilates developed his signature low-impact method while imprisoned as an enemy alien during World War I, using hospital beds to rehabilitate fellow inmates. A century later, that survival-born exercise routine has evolved into a global fitness juggernaut, anchoring a wellness market now valued at $120 billion.

The practice migrated to Manhattan in 1926, finding an early foothold among professional dancers before exploding into the mainstream during the late 1990s. Today, the industry is defined by the reformer apparatus—a spring-loaded frame designed for precision movement—and a growing demand for accessible, high-quality instruction. Heather Andersen, who co-founded New York Pilates in 2013, sought to break down the barriers of private sessions by creating a studio environment as accessible as a local gym. Her brand now operates eight locations across New York City and the Hamptons, relying on debt financing and organic growth rather than outside venture capital.

Success in this space hinges on the human element. Education manager Kat Anta emphasizes that the method's adaptability allows it to serve everyone from elite athletes to those recovering from injury. This versatility, paired with a surge in social media visibility, has turned Pilates into a cultural staple. Andersen maintains that the core product remains the expertise of the instructor, noting that scaling requires a deliberate focus on training. As the sector expands, its resilience is increasingly tied to the creation of third places—physical and digital communities that provide the human connection often missing in modern fitness routines.
