NO.
Your body needs all your calories to fight germs. If you work out, here are some of the potential problems:
-you won't be able to lift as much; your body is going to try to use more calories to fight germs and not bother to think about lifting weight.
-you might faint while lifting. REALLY BAD.
-your fever might get worse because of the extra stress, causing you to go to the emergency room.
That's just the beginning. Don't do it.
