The Fitness Center at The Langham, New York, Fifth Avenue

"On a stretch of Fifth Avenue between Grand Central Station and Herald Square, this luxury Midtowner -- formerly the Setai -- lures weekenders and worker bees with a range of contemporary, warm-hued accommodations featuring marble bathrooms, rain showers and flat-screen TVs (some also boast views of the Empire State Building); on-site indulgence comes care of the full-service spa, cocktail bar and Italian eatery Ai Fiori -- you can work off the calories from the latter in the 24-hour fitness center"

"Catering to how things are done in NYC, the fitness center is open 24 hours a day and you can book a trainer or yoga instructor to help you with your workout"

"Not enough? On-site is a celeb-helmed restaurant (Ai Fiori from Michael White), a massive spa and gym, and the Julian Farel salon"

"For an early morning workout during your New York excursion, there’s an impressive 24-hour gym that’s fit for athletes and insomniacs alike"

"The marble-floor bathrooms come with deep soaking tub and TV-embedded mirror, with additional hotel perks including early check-in or late check-out, good-sized gym, in-house luxury spa and Michael White's Michelin-starred restaurant Ai Fiori"

"The 24-hour gym is well-equipped"
