This looks like a good fit for FiDi:

Health-club chain Fitness International signed one of the year’s biggest retail leases at AmTrust RE’s 58 Maiden Lane — a three-level, 36,650 square-foot home for a new “Club Studio” concept.

The club will provide “next-level” amenities and boutique fitness classes together in a single, state-of-the-art facility — including steam rooms, cryotherapy, infrared saunas, personal training and a retail store.

It will replace what was previously the Zeytuna food market.

About 7,500 square feet will be on the ground floor of the building, a fully-leased, one million square-foot office tower.

AmTrust president Jonathan Bennett called the Fitness International deal “a pivotal moment in the revitalization of Downtown. Club Studio is a one-of-a-kind experience that will cater to both local residents and our commercial tenants.”

The tenant was represented by Chase Welles of the Shopping Center Group and John Kalamaras of the RealSource Group.

The landlord was repped by AmTrust CEO David Abrams and Eliot Goldschmidt, Jeff Jacobson and Brandon Miller.
