about the disinfectant wipe down at the end of cardio, i think that is just stupid. you are going to need more than a bottle of some 'cleaning solution' in order to prevent disease, you need to wash your hands after you work out.
therefore I refuse to wipe down machines because its a waste of time.
plus wiping the machines seems like some kind of new fad now or something. It doesnt some like this was that big a deal a few years ago, and now gyms are obsessed about it.
