6. Zenergy Health Club & Spa
Due to a very high $15,000 initiation fee, Zenergy Health Club & Spa more than doubles the amount you’d spend in the first year comparing to the previous gym. This gym in Idaho boasts an amazing view and is not only limited to a gym. They also have facilities like tennis courts, freshwater and saltwater pools, and even private facilities for those wanting a poolside party. There are many other things to do with this place being a health club & spa.
