If you have ever worked out when feeling sick, sometimes you can feel a lot worse, while other times you can feel better.
You should avoid working out with a fever but having minor congestion or a minor headache may be perfectly fine.
While ill, you should drink a lot of water and take vitamin C as well as Zinc tabs which can help you feel better sooner.

Getting sick can throw off your fitness routine, and for those who love working out, that’s a big bummer. It’s tempting for fitness enthusiasts to continue their usual routine even while battling a cold, but certain symptoms indicate that you should allow your body to recuperate before exercising again.
Note: If you feel sick, you should not work out in a gym, fitness studio or any area where you’ll be in proximity to other people. Even if you only have minor symptoms, it’s safest to work out at home or go for a walk in a lightly populated area. With that in mind, here’s when it’s safe to exercise and when you should rest.
