Sick

When you are sick, you should rest and not feel guilty. Time enough to exercise when you are feeling better.

I actually worked out when I caught my last cold and the duration of it was only 4 days instead of the usual 7-10 days. Apparently it helps to boost your immune system by helping to flush out toxins through your sweating. However, if you have the flu, stay in bed.

Rest. Any pushing of the body will just result in expending energy your body needs to heal itself. It's a legitimate reason not to workout.

I am currently sick and don't feel guilty at all for NOT working out.

I worked out on Wed. felt fantastic, and BAM over night, seriously sick. Fever, flu type stuff.

Rest, your body needs it to heal.

the above/below the neck rule is quite helpful

sick above the neck, i.e. cold (without a fever), sniffles, maybe a mild cough or a runny nose kind of thing - training is usually okay and some people find it actually helps

sick below the neck, i.e. fever, chest infection, nausea, vomiting, diarrhoea - rest and recover properly before training again

This rule usually helps, but if you find that a cold is lingering on when you'd normally have recovered, a few days off training may help, even though it's all above the neck.

Listen to your body, if you can hardly get out of bed then stay in bed!! that's definitely below the neck sick!!

I've just been sick "below the neck" and unable to work out for 3 weeks! I did try a couple times and just felt dreadful the next day. OP, I vote let your body rest, your trainers aren't going to run away from you

It depends on the kind of sick. "Can't crawl out of bed" means you STAY in bed. A cold that you would still go to work with, I would would still exercise, although maybe a little less intense. "Sick" (or injured) isn't an EXCUSE to not exercise, it's just a limiter of what you can and can't do over a set period of time.
