I'm suffering severe body pain and a dose of viral flu with averrsion to solid food. how to regain my body fitness?

Recovery process: Influenza has hallmark symptoms of body aches and pains, as well as fever. People generally do not want to eat much when ill, but fluids and soups may be good for nourishment. The best way to regain fitness is to rest, stay hydrated, and allow yourself to recover. Tylenol (acetaminophen) or Motrin may help with body pains and fever. Depending on how ill you are, it may take a week or so to feel better.

Wait: Until the flu has abated. Taxing your immune system during a viremia will set back fitness levels and delay recovery. The rate of aerobic recovery is higher for those already fit. Don't worry..And get well first!
