I am 17 years old and have asthma. I would like to start a cardio program but i do not want to over do it or anything. If anyone could give me some tips that would be greatly appreciated.

I have asthma, too. Just take your medication (especially your inhalar before you go running) and you should be fine. Unless you have bronchitis or pnemunia then asthma is really only a petty excuse to be lazy.

Just run a mile every day and try to up your time from your normal time once every week. (12 minute mile jog on Monday - Friday, try to beat that Sunday or something).

You're not going to get better unless you push yourself. The heart is a category 3 muscle and needs to be worked regularly for improvement.

I would also suggest you try out different types of cardio to keep your body from acclimating too much. Run long distance one day, run sprints another. I like biking since it is low impact on the knees.

Sound advice there. It's always best to mix it up a bit. If you have access to a punching bag, I would recommend boxercise. You'll be amazed at how tired you quickly get from punching a bag for 10 mins.

Do that and, if you can, add swimming and you'll be a cardio machine, mate. If there was one exercise I had to pick from that it would be swimming. NOTHING beats swimming in terms of cardio improvements.
