People go to church to pray, why not go to work out too? This gym in New York used to be a place of worship and now treadmills are completely

dominated by beautiful stained glass windows. 

This bouldering gym took a location that no one wanted and used it to its advantage. Decommissioned silos were transformed into rock climbing areas and can be used by members

to improve their skills. 

This gym has been refurbished from an old mansion. Many original pieces like chandeliers and woodwork remain. You can head to different sections of the mansion depending on what type of

fitness you're looking for (cycling, TRX training, etc.). 

If you're into yoga and churches, then this is the place for you. This (maybe hunchback-friendly) cathedral is turned into a yoga studio every Tuesday. 

If you want some relaxation and a little bit of wine mixed in with your exercise, then this health spa is the place to go. The mansion-gym has a distinct

vineyard feel to it that you're not going to find anywhere else. 

If you love to workout in a box and have a deep desire to visit Europe, then you'll need to make a pit stop at this gym. Everything you need

to lift is here, surrounded by beautiful church architecture. 

Does an amphitheater count as a building? For the purpose of this list it sure does! Every summer the theater becomes an outdoor fitness group class for anyone brave enough to take it

on.
