Finding a Good Gym in NYC?

Wasn’t sure if there’s a place for discussing this stuff - my bad if there is.

Anyone know a good place for serious lifting in Manhattan, preferably Upper-West-Sideish? Most of the chains seem to be crazy expensive ($80-100/month) and focus mainly on the cardiocardiocardio crowd. I have a membership at Columbia University through a family thing, but that’s ending at the end of this month. The only other place I know of to lift is a pretty sketchy public gym up in Riverbank State Park. But there must be impoverished lifters in a city of 8 million, where do y’all go?
