EXERCISE WHILE SICK?
How do you know if you are too sick to exercise? Use the neck rule: If your symptoms are above the neck, such as a cold with runny nose or scratchy throat and you feel up to it, it should be OK. If your symptoms are below the neck, such as a deep cough, an upset stomach, aching muscles, fatigue, or fever, let your body rest. Listen to your body. When in doubt, ask your doctor.
