Best types of training for those with asthma?

Hi all... I am new to this forum and seeking information that I haven't been able to find elsewhere. But surely someone knows.... anyway... I have mild asthma, but it is induced by heavy exercise, and seems the worst when we do sprints without much rest, especially with zoomers. My question is, how can I train the hardest without kicking off my asthma? What are the best sorts of sets or training practices? (And how can I modify existing sets without messing up my lanemates?). Sometimes our coach will ask us to do sets where we severely limit our breathing. Are these good for me or bad?? I do have an inhaler, but it doesn't seem to help with the exercise-induced asthma (only the cat-induced type). And I am always careful to warm up and cool down. Thanks in advance for any suggestions! Roberta
