I have done this a lot and was not as fun as I thought it would be. It used to
cost a small fortune (think Golds in Santa Monica or is in Venice Beach now?)
and the paperwork and all the people that won't move out of your way, or
give up a machine you want to use (the last part is a joke). Seriously, I never
enjoyed it that much. Sure you get look at some new hide and try out some
new machines but if want an in-and-out workout like you get a home, I never
got it, it was always a chore to me. But hey, that's just me.
