Fever is a sure clue to NOT workout, take a break it'll do you good, take your vitamins, go to bed... If you feel just OK, go light on the exercise for a few days...
Another thing, if you go to a gym, and you are sneezing and coughing, for me, this has to be THE worse turn off!! Stay home for gosh sakes don't go spreading your germs all over the machines...It's a pet peeve I know
