9.Breathe Better
Even if you have a lung condition, regular cardio exercise can help improve your breathing. If the gym’s not your thing, a walk, jog, or a regular tennis game can do the trick. Just make sure to talk to your doctor about your exercise plan if you already have breathing problems.
10.Help Fight Germs

That’s partly because it helps blood get around your body better, which means germ-fighting substances get where they need to go. Scientists continue to study exactly how exercise helps boost the immune system — your body’s defense against germs.
