Equinox Fitness is an American luxury fitness company with its national headquarters in New York. Equinox operates five separate fitness brands: Equinox Fitness, PURE Yoga, PURE Fitness, Blink Fitness, and Soul Cycle. Equinox is a subsidiary of The Related Companies, one of the largest real estate development and property management companies in the United States.
The first Equinox Fitness location opened in New York's Upper West Side on September 23, 1991. In 2006, Related Companies purchased the Equinox Fitness from North Castle Partners and J.W. Childs Associates. The original owner was the Errico family. In 2008, Equinox brought Pure Yoga to the United States from Hong Kong, which it operates separately. The two brands do not cross promote each other.
