How to deal with exercise-induced asthma?

I've read some of the posts regarding asthma already, but all I found were along the lines of "go to a doctor and get an inhaler" and "asthma gets better with running." I already use an inhaler and such, but what I really wanted to know is what other things can I do to help me overcome asthma? I know swimming is an option. Anyone else have any ideas?

EDIT: I appreciate all the answers! Thank you guys!
