Like swimming, yoga, Pilates and weight lifting, walking is a low- to moderate-intensity activity that most asthmatics will find is entirely tolerable. In fact, one study found that adults suffering from asthma who walked three times a week over the course of 12 weeks (30 minutes at a time with five minutes warming up and five minutes cooling down) were able to improve their asthma control and increase their fitness levels without instigating an attack. Just be sure to keep outdoor allergens in mind.
