For those who are constantly in transit, a big hump to staying healthy is to find time to work out. Even if the time is there, hotel gyms can leave much to be desired. A couple of worn treadmills and a Bowflex do not a gym make.

That's not the situation everywhere, and there are some killer hotel fitness facilities out there to make any health-conscious businessman swoon. We're talking endless rows of cardio machines, pools, personal trainers, full-sized basketball courts, fitness classes and rock-climbing walls. Spa services are available for a bit of post-workout R&R. With amenities like these, there might be no reason to bother joining a gym back home.
