Keep your distance
Crowded fitness classes make it easy to inhale germs – particularly influenza. As a method of defence, you might want to consider getting the flu shot. You can also try to keep a reasonable distance (for example, two arm lengths) between yourself and anyone with a cough, as they are likely contagious. When heading for the cardio equipment during non-peak periods, choose a machine that’s not right beside someone else.
Wash your hands regularly
Wash your hands thoroughly with soap and water, or use an antibacterial hand gel before and after class. Regular hand washing is a habit worth developing year-round, but particularly important during flu season. Doing so prevents you from bringing germs into the gym, or leaving the gym with germs you may have come in contact with there.
Avoid touching your face
From using free weights to touching the buttons on the cardio machines, your hands are likely the part of your body that have been in contact with germs the most during your gym workout. Try not to touch your face, since germs you come in contact with can wind up in the openings of your nose, ears and mouth. Make sure to have a clean towel with you so you can wipe sweat away from your face without having to use your bare hands.
