Some people lived in the house behind us where I grew up - the man owned some kind of construction company and always had guys working on his house (I mean constantly), and the wife, and aerobics instructor, made a whole business of opening and closing gyms. Never pay long term unless you really really really trust a gym. It is easy to lease some equipment, rent some warehouse space, take in those 1 or 2 year memberships, and then fuck off with the money, and some people make a whole career out of it.
I hated those scumbags, they moved in behind us after some nice old folks moved out, and it was pool parties every weekend with their phony friends. They even named their cat "Izod."
"Izod, Izoooood!"
Like something right out of "That 80's Show."
