Check your neck

If you're not feeling well, there's a rule of thumb—the "neck rule"—for figuring out when it's safe to exercise or head to the gym. If your symptoms are above the neck—a stuffy nose, scratchy throat, and headache—you probably have a head cold and can safely hit the treadmill. If you have a fever, achy body, or lung congestion, however, it's probably the flu and a sign to rest up. (Still, experts warn that this rule isn't foolproof, and it's best to use your judgement when it comes to taking time off from exercise.)
