I have very mild asthma, with some scarring. On my home peak flow meter, I average 400, in a narrow range (never lower than 360, and that's infrequent; seldom more than 430 but sometimes higher). Which level of resistance do you recommend for me?
Please choose the model based on your level of activity. Wellness (green) for infrequent exercisers or people with respiratory problems; Fitness (blue) for regular exercisers; Sports Performance (red) for serious or competitive athletes. You may also consider the classic model POWERBreathe® 95-1006.
