Our gym has sanitation wipes to use. I wipe down the machines before and after I use them. I wipe them down even if I see others wiping them down before I use them. My gym was once empty on the sanitation wipes, so I went into the bathroom and got a soggy paper towel with soap in it.
I am also sure to NEVER touch my eyes, mouth, face, etc. That's how you get sick.
If you notice a lot of people tend to cough when they're running on the treadmill or otherwise working out heavily. Just breathe through your nose and don't touch your face until you wash your hands thoroughly with soap and warm water.
But yeah, I agree. It's disgusting when people go to the gym sick, or otherwise go to a public place. When I worked at a grocery store people would show up sick all the time, cashiers and deli workers included. They didn't want to miss out on pay, and I'm guessing that's the same reason people go to the gym sick. They pay for it, and don't want to miss out on their money's worth or their exercise routine (when sleeping in bed would do them more good). It's like college kids showing up to class sick because they feel like they can't miss it, and paid lots of money to be there.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
