2 exercising when sick Or injured While exercise can strengthen your immune system, do sit it out when you
are feeling unwell or feel pain in your muscles or joints. While a cold or sore throat may not rule out a short jog on the treadmill, it’s probably a good idea to skip your exercise class if you have a fever, flu, cough, muscle aches or chill, vomiting or diarrhea.
