14. Equinox
No. of locations: 91
Equinox is one of the fanciest gyms out there. It is a luxury fitness company founded in 1991 in NYC. Apart from being in the top gyms with most locations nationwide in 2018, the company has also announced expansion by the opening of hotels in New York and Los Angeles by 2019. Of course with the attribute “luxurious” goes the high price as well. But if you are ready to give a nice sum for your training, that would be money well spent.
