Researchers recently took samples at three different gyms to see how gross the equipment was. It turned out almost everything was pretty disgusting, and 70% of the bacteria they found was the kind that can make you sick.
Three things that were absolutely COVERED in bacteria were free weights like dumbbells . . . the handlebars on exercise bikes . . . and the handlebars on treadmills.
Just to give you an idea, here's how gross they were compared to a few other things we touch every day.
Free weights had 34 times more bacteria than a lunch tray at a cafeteria . . . 64 times more than an average water faucet . . . and 362 times more bacteria than a TOILET SEAT. Which AREN'T actually that filthy.
This makes me VERY happy to have a little gym in my garage...it's only MY germs in there!
