This would be nice. To sweat like a pig, because pigs don't sweat. But that wouldn't be a good workout soooo. I would say, "sweat like a Horse and look like a fox." Because, unlike a pig, horses sweat a ton when they have really worked out!
Some people exercise by running, others exercise by using their right to vote. This picture shows exercise somewhere in between. An escalator going up to a fitness center definitely belongs in our funny signs collection.
