Performance Is Not About Lung Capacity, Stupid

A curious and asthmatic reader of Outside magazine wants to know how he can improve his lung capacity, and Outside fitness answer man Chris Carmichael has an answer, and a warning.

unless you increase the rate of oxygen transport within the lung
tissue, you would not actually increase performance, as you would not
deliver more oxygen to the working muscle faster.Read more at Outside online.
