I've been a member of NYSC for four years and it's been a great gym for me. Most of the locations open as early as 5am and are open till at least 10pm. The classes are varied and great, and the machines are kept in good condition and are updated as needed. Most types of membership will let you go to any club you want (some only during off-peak hours) based on what's convenient for you and where you are according to your schedule. There's one in Commack that you may want to consider checking out - I'm sure you could even walk in and say you're thinking about joining, and they'll show you the place and let you work out for nothing! It's definitely been one of my best investments, by far. I highly recommend it!
