I have a slightly elevated body temperature, congestion in my chest, and a bad cough, but I feel very strong and healthy – hard to imagine, I know. I really want to work out, my body craves it as does my mind, but I fear I’ll turn my little cold into pneumonia. I’ve read of the “above the neck rule” which means if your symptoms are above the head (stuffy nose, etc) you’re fine to work out, but if they are below (fever, chest congestion) you should avoid exercise, so I'm staying clear of the gym for now. I’d like to ask how others determine if they are too sick to work out.
