Fitness centers tent not to have great physiques, with easy-scrub finishes and unflattering fluorescent lighting. If you’re lucky, there’s a zingy accent wall. Charting a different path, the Equinox chain is infusing its brand with an industrial-luxe sensibility that’s both studly and sybaritic. INC Architecture & design masterminded a loft-like outpost in a former cardboard factory in Brooklyn, employing lavish finishes to give way-finding and space-making some real muscle.

In the lounge, a dynamic mosaic wall suggests water and sky with variegated tones of blue and white. By repeating the colors in the rich blue furnishings, INC created a feeling that’s more intimate than institutional.
