Must i exercise outside if i have exercise-induced asthma?

See below: No. You can certainly exercise in a gym or at home with equipment. However, the exercise inside may trigger your symptoms as well.

No....: If you have exercise-induced asthma, you can exercise wherever you want but you should be pre-treated with a bronchodilator inhaler before you exercise. The inhaler should also be available post-exercise in case you develop symptoms of asthma once you stop exercising.
