TweetHELL YES I've been sick! IMO, this season is going to be a mutha for slow healing cold infections. I avoided being sick for 2 years, then 3 and a 1/2 weeks ago got the worst snot stuffed head cold that slowly past from the head to my chest. I'm still hacking up throat oysters a few times a day, and lose my voice to dryness at least a couple times a day (regardless of water intake, juices, cough drops, etc).
Swine flu for some reason really doesn't have me worried... but common cold infections seem to be on a major increase, and they are more and more persistent.
So far as training, my rule of thumb "generally" is so long as there is no fever, or excessive coughing - then I go ahead and get in the gym and at least go through the motions. Intensity will be lacking when your body is fighting infection, but I've found that continuing to train helps to maintain things and allows for a quicker rebound to full strength once infection begins to weaken.
I see more sick people (colds, flu) now than I have in past years.
