A big reason folks join a gym is to lose weight. But if a patron of the female-oriented Body Exchange gym in Canada gets too svelte they are liable to lose their membership.

That's because the workout facility, which caters to a plus-sized clientele, bans all skinny women. They do so, according to the gym chain's founder and CEO Louise Green, because slim women "bring down morale."

Body Exchange member Lisa Schaffer is big supporter of the policy, saying she is glad there aren't "tiny little Lululemon people running around."

Some exercise experts believe that creating a safe, comfortable environment for overweight people to workout is essential to getting them in shape.

On the other hand, could you imagine the uproar if a gym banned fat people?
