With 30,000 health clubs across the country, Americans have their pick of where to work out. Some fitness clubs, however, are simply a cut above the rest.

The country’s most luxurious and exclusive fitness clubs are more like health oases, where you might find Olympic-size pools, indoor tennis courts, private changing cabanas, steam rooms, celebrity trainers and even retinal identification scanners.

The price of entry to most of these health sanctuaries is steep, with the combination of initiation fees and monthly dues ranging from several thousand to $30,000 a year. This is a far cry from the median yearly cost of the ordinary fitness club, which runs about $775, including an initiation fee. In most cases, there is an initiation fee and a monthly charge. In one case, there is simply an all-inclusive annual fee.

So, what are the most luxurious fitness clubs across America? Click ahead to find out!
