Cardio is a huge help. Luckily for me, my asthma doesn't prevent me from doing cardio. It makes cardio tough as shit and it prevents me from getting any faster (been running a 24 minute 3 mile for 6 months now), but I can still handle it.
If you can't handle the breathing requirements of jogging, try walking and bike riding. Low impact and easy to do, but they get the heart rate up.
