Now that we're well into 2016, there are still a few high-end homes to help fulfill those New Year's resolutions. Namely, mansions with fitness facilities on their well-manicured grounds. While these properties are pricey, you can realize a modicum of savings when you cancel your fitness club membership. Plus, there's no more excuses when the gym is only steps away. Right?

Increasingly, a well-appointed home gym has become a high-end perk that gets luxury buyers all hot and sweaty.

"Home gyms are definitely in demand," says Joel Goodrich, a luxury real estate specialist with Coldwell Banker Previews International. "Along with media rooms and wine tasting rooms, they are the kind of amenity that distinguishes the ultraluxury from luxury properties."

So, no surprise, homes with extravagant gyms tend to be extravagant in all respects -- with high price tags to match. Pull on your spandex, and prepare to pump some iron in these eye-popping properties with equally eye-popping fitness rooms. Don't forget to stretch first.
