Chelsea Piers Fitness Signs Lease for New Club with TF Cornerstone at the Developer's Latest Office-to-Residential Conversion, 135 East 57th Street

47,000-square-foot deal underscores Chelsea Piers Fitness' strategic growth across New York City and its sustained partnership with TF Cornerstone

NEW YORK, Nov. 17, 2025 /PRNewswire/ -- Chelsea Piers Fitness, New York City's leading premium fitness brand, announced today that it has signed a long-term lease with TF Cornerstone (TFC) to open a new club at 135 East 57th Street, advancing the brand's strategic expansion across the New York Metro area. The new 47,000-square-foot location — located on the ground and lower floors of the 32-story Midtown East building recently purchased by TFC as its newest office-to-residential conversion project — will reinforce Chelsea Piers Fitness' presence in one of Manhattan's most dynamic commercial corridors and reflects its ongoing commitment to developing elevated, community-driven wellness destinations in high-demand neighborhoods.

This marks the third partnership between Chelsea Piers Fitness and TFC, underscoring a long-standing relationship built on shared values around community connection, innovative design, and creating environments that enhance how New Yorkers live and move today. Located at the corner of East 57th Street and Lexington Avenue — two of Manhattan's most prominent thoroughfares — the new club will sit just two blocks from the major 59th and Lexington subway hub, offering exceptional accessibility to both Midtown East's work-life community and the Upper East Side's residential core. The forthcoming location will deliver the brand's signature premium fitness experience, blending world-class training, recovery, and social spaces designed to energize the surrounding area.

"At Chelsea Piers Fitness, our growth starts with quality — the right neighborhood, the right space, and the right partners," said Sam Bernstein, Chief Operating Officer of Chelsea Piers Fitness. "For more than three decades, we've focused on creating spaces that grow with their communities. Our continued partnership with TF Cornerstone reflects a shared commitment to investing in clubs that elevate well-being and foster real human connection. This new location marks another milestone in our disciplined expansion strategy as we continue to strengthen our presence across the tri-state area."

Following back-to-back openings within TFC residential buildings in Downtown Brooklyn at 33 Bond Street and 595 Dean Street in Prospect Heights, Chelsea Piers Fitness most recently debuted a 60,000-square-foot club at One Madison Avenue in partnership with SL Green. Each location in its growing portfolio reflects the brand's evolution over the past three decades — intentionally designed to mirror the character of its surrounding neighborhood while honoring Chelsea Piers' legacy of fostering connection, movement, and community. As one of New York City's most trusted fitness institutions, Chelsea Piers Fitness continues to shape modern wellness by creating spaces that function as true third places — environments where people can train, recharge, and belong.

"Our continued partnership with Chelsea Piers Fitness reflects our commitment to fostering long-term relationships with best-in-class operators who enhance the quality and vitality of our properties for both residents and the neighborhoods in which they're located," said Steve Gonzalez, TFC's Vice President of Retail Leasing. "135 East 57th Street represents an exceptional opportunity to bring a premier wellness experience to the base of our latest conversion project that further contributes to the energy of this desirable area of the city."

TFC will begin revitalizing 135 East 57th Street into more than 350 market-rate and affordable apartments in early 2026. This newest retail lease marks one of several Chelsea Piers Fitness developments heading into 2026, as the brand enters its latest growth chapter. Further details about design, amenities, and renderings will be revealed at a later date as development progresses.  For more information about Chelsea Piers Fitness, visit fitness.chelseapiers.com, or follow on Instagram @chelseapiersfitness.
