To put that in context, a typical toilet seat has only 3,200 bacteria cells per square inch, according to the report. That means the average dumbbell has 362 times more germs than a toilet seat. The treadmills and bikes were even worse offenders, with 417 times more bacteria than a toilet seat.

Of course, not all kinds of bacteria make you sick, but many can cause pneumonia or infect your skin, ears, eyes, or respiratory system. Next time you work out, bring along some disinfectant wipes. You feel the burn, I’m feeling my stomach turn.
