It’s no secret that bacteria can be found at the gym. That’s why we’re encouraged to wipe up after we use machines! But just how MUCH bacteria are we dealing with? The dumbbells at an average gym have 362 times more bacteria than a toilet seat! Even worse, handles on bikes, treadmills, Stairmasters, etc., have 400 times the amount of bacteria found on a toilet seat. Yuck! (Photo: Women’s Health)
