Boston Sports Club, it's the only gym that is close to my current residence - in the city. It's a good gym though, even mix of cardio and serious weight lifters..... Since it is so expensive, and there are a lot of professionals there, I don't have to deal with many of the goofs we talk about on the board.
I used to work out at my college's gym - ( Boston University), and that gym is gigantic. Also, I was a member of the South Boston golds, but the drive there became tiresome. To me gyms like Golds are overrated.....give me a bench, some hammer strength machines, dumbells and a squat rack.
