Yeah .... I was never a fan of that idea .... let's go to a public gym full of strangers that regularly spill or can potentially spill their bodily fluids.
I go a bit farther than most people and bring disinfecting wipes to wipe down before and after I use the machine. After seeing a gym employee pour half of one cleaning spray bottle into another and fill them both with water from the drink fountain, I decided I didn't trust gyms to have proper cleaning supplies.
By the time I die I will probably have spent a full gym's worth of equipment in wipes, but for now I still can't afford a home gym outside a couple free weights.
