What if Gyms had "Fats Only" Sections? Really. The fats would prefer it so they wouldn't have to be embarrassed in front of actually fit people, then if they ever become actually fit they can move onto the fit section. Then the people who are actually fit wouldn't have to be bothered by fats smelling up all the machines.  They could disguise it as "beginner area" or something, but the message relayed is the same. We all know how big of a deal fats would make out of "Fats Only" section.
