Bare minimun as far as gyms go..first time i went i. People are always spraying diluted poison out of filthy bottles ..disgusting! Would be alot nicer if they just had one of the staff going around misting something a little safèr onto the machines here and there and require towels. I researched the stuff they spray not good.. took pics of the bottles..look close..eeewww i was too afraid to touch, also being astmatic the last thing you need is stuff being sprayed around you. One other thing..actually let woman in there that had a dog in a carriage lol..must have been one of those freaks that claim they have an emotional need to have their dog w/them..i wonder what the deal was with the guy that had the parrot?..no i'm not kidding! Lol
