The Best Hotel Gyms

 Forget the days of a cramped closet filled with a creaking air conditioner and treadmill that hasn't been updated since Clinton. Smart hotels know keeping heads in beds often means making sure those heads get their daily dose of exercise. And the best hotels go a step further. We're talking basketball courts, Olympic-sized pools, DJs, ridiculous design, views that beat your bedroom, custom classes, and even loaner clothes. We're talking the best hotel gyms around.

Amanpuri, Phuket, Thailand
And you thought your local Equinox was nice: Andaman Sea views from this glass-walled, rare-wooded, 3,800-square-foot gym will make you salivate as you sweat. Hit the machines or pump up with a custom Pilates program. Amanpuri.com

The Perry, Miami

The Gansevoort Miami might have changed names, but its clubby in-house David Barton Gym remains, as ever, over-the-top, with 42,000 square feet of fitness space, intense Moroccan décor, and SoBe scene aplenty. PerrySouthBeachHotel.com; $15 per day for guests

The Loews, Atlanta

Run by Exhale Spa -- nothing beats a good Core Fusion beat-down -- the huge space and co-ed hammam is also open to Hotlanta?s well-toned locals, so you might very well meet a bar bud on the ellipticals. LoewsHotels.com/Atlanta

Shangri-La, Tokyo
A 29th-floor heated lap pool overlooking the Imperial Palace? Check. Steam room and sauna? Check. Loaner gym clothes, sneakers, and swimsuit? Just tell ?em your size. As long as you?re not a giant , there?s no excuse not to workout. Shangri-La.com/Tokyo

Radisson Blu Aqua Hotel, Chicago

Sharing space with condos in the architecturally awesome Aqua tower has its benefits, namely a half basketball court, outdoor running track, indoor and outdoor Olympic-sized pools, plus scads of all-new top-of-the-line equipment. RadissonBluChicago.com
