Do you need a membership to work out in the gum or is it an open gym?

Members only but they don't lock you up in a contract

You can go online to their website and print out a 4 day guess pass. Joe is right they will like almost force you to sign up but just hold your ground and tell them you want to try out the gym first.

Yes. But they do offer walk in and trial but you know like all health clubs, they will almost forcefully try and sell you a membership.
