More About Measuring The Chest – Strength Magazine – September, 1917

As I said before, I believe that the importance of chest expansion is over-estimated. Quality counts for as much as quantity when we are considering the strength of a muscle, and the same thing apparently applied to the lungs. We have, for instance, two men, each with a lung capacity of 250 cubic inches, and the first man can swim, run, walk or row long distances without being winded or becoming exhausted in any way; and the second man, despite the fact that his lung capacity is just the same, becomes winded after a slight amount of moderate exertion.
