Chicago - A gym in Chicago has one big rule: no skinny people allowed!
It's called Downsize Fitness.
In order to join you need to be 50 pounds overweight.
The owners say their goal was to create a place where people wouldn't be intimidated.
The gym even has permanently fogged up windows, so people outside can't see who is working out inside.
The owners say once a client loses the weight they are allowed to stay on as a mentor new clients.
