Adidas is spending big to transform unused office space in iconic areas into top-tier training clubs.

The sprawling Starrett-Lehigh Building on the West Side is embracing the fitness trend with the upcoming launch of the Adidas-branded 601 Athletic Club, spanning an impressive 15,000 square feet.

The new facility will be added to the existing 100,000 square feet of tenant and public amenities, which already include Marcus Samuelson’s renowned restaurant, Hav + Mar, the recently opened Olly Olly Food Hall, and a public art and event space that recently hosted a Basquiat exhibition.

The 601 Athletic Club will be equipped with top-of-the-line Peloton equipment and will offer exclusive programming, including yoga and pilates classes, a walking club, and “no-cooking” cooking classes.

As part of the Starrett-Lehigh Building, a 1931 landmark featuring a stunning industrial-modernist design, the addition of the 601 Athletic Club enhances its allure as one of the city’s largest commercial buildings, encompassing an impressive 2.3 million square feet.

Among its prominent office tenants are Ralph Lauren, McGarry Bowen, Fashionphile, and Wheels Up. Currently 73% leased with additional deals in the pipeline, the building’s success under RXR’s ownership since 2011 has seen asking rents rise significantly from $30 to $70 per square foot.
