The name is not ours. SOUK, the yoga studio one floor above SoulCycle’s door on West 27th Street, describes its own address as the Sweat Corridor, and a walk along the block explains why: a cycling room, a yoga room and a thirty-nine-thousand-square-foot club sit within a few doors of one another, and a boxing gym, a hot room and three reformer studios are a short walk beyond. Nobody zoned for this or planned it. The buildings did it.
They were put up for trade. After 1900 the blocks north of Madison Square filled with slender loft buildings of twelve to eighteen storeys, built for wholesale merchants: separate freight lobbies, high ceilings, and deep floors interrupted by as few columns as possible. By 1939 the WPA Guide to New York City found the district crowded with the factories and salesrooms of the toy, novelty, silk, woollen and men’s clothing trades. Most of that business eventually left the country, and the upper floors passed to photographers drawn by the low rents, and then to anybody else who needed a large, open, affordable room above the street.
A fitness studio needs exactly that. A column-free floor takes a row of bicycles or reformers; a high ceiling takes a raised arm and the heat of a full class; a freight lift brings up machines too heavy for any staircase. The economics favoured height as well. When Amanda Freeman opened the first SLT in 2011, she took a nine-hundred-square-foot room on the seventh floor of a Midtown building on a thirty-month lease, and only after the retail market softened in 2015 did she begin taking space at street level. Upper floors were where a new studio could afford to begin, and this neighbourhood had more of them, in better condition, than almost anywhere else in Manhattan.
Clusters then feed themselves. A rider leaving SoulCycle passes the yoga studio on the way down the stairs; a club member who wants a teacher to herself finds one around the corner. The moment the arrangement began to look permanent came in 2019, when Equinox signed a twenty-year lease for the first three floors of a remodelled loft building on 27th Street, sharing the address with an architecture practice and a film company. Nobody signs for twenty years on a fashion.
The machines have histories of their own, and the oldest is a New York story by adoption. Joseph Pilates, a German physical trainer living in England, was interned as an enemy alien during the First World War and spent most of it at Knockaloe on the Isle of Man. The founding story, which historians treat with some caution, has him on the camp’s hospital ward, fixing springs to bed frames so that patients who could not stand could still work against resistance. He emigrated in 1926, met his future wife Clara on the crossing, and opened a studio with her on Eighth Avenue; the sliding, spring-loaded carriage he called the Universal Reformer is the machine at the centre of the studios on this list. The longer, harder variant at SLT was built in Los Angeles by Sebastien Lagree, and Freeman brought it east with the stated aim of giving Pilates the pace and music of a cycling class. What she sold was not a year’s membership but fifty minutes, and that unit, the single booked class, is what most of the Corridor now trades in.
The heat arrived by several routes. bodē, at 23rd Street, teaches the fixed twenty-six-posture sequence first popularised as Bikram yoga, which a federal court ruled in 2012 could not be copyrighted — the reason the same series is now taught under many names. ID Hot Yoga, three minutes north of the hotel, builds its heated classes around strength and functional movement instead; Humming Puppy keeps its room merely warm; and SOUK does not heat its room at all. Four temperatures, and four ideas of what a class is for, inside ten minutes of this door.
Which brings us to the practical point. The Corridor is extraordinarily good at selling a visitor a single hour and poor at selling a day: almost nothing here is a walk-in, and the hour you want may be the only class in a long morning. Read the timetable rather than the opening hours, book the evening before if you can, and let us make the booking if you would rather not. This list also sits directly opposite another in the collection — Spas & Bathhouses is about being worked on, and this one is about doing the work. Plenty of people use both in a day, in that order.
