How to work out with exercise induced asthma?

Modify as needed: Use albuterol or Levalbuterol inhaler or singulair (montelukast) before exercise. If your asthma gets worse with low humidity, temperature extremes, or outdoor allergens, limit exposure to these. Breathe in through your nose instead of your mouth. You can try any exercise, but if aerobic activities cause symptoms too much, weightlifting and swimming are excellent alternatives. Most important, know your limits.
