To quickly assess the difficulty of the text, read a short excerpt:
Fill your lungs as deeply as you can, and you cause the ribs to rise and to bulge forward. The DEVELOPING LUNG POWER 115 intercostal muscles facilitate this expansion of the chest, one rib being pulled upward and driven for- ward by the same movement of the rib above it. The diaphragm does its share by rising and forcing the lungs to expand outward. The ribs are obliged to accommodate themselves to the movement. The in- tercostal muscles become stronger (through this con- stant exercise) and th...e costal cartilages are forced to stretch in order to accommodate this new demand on their expansion. In time, by repeated exercise, the cartilages permit of great increase in size of the cav- ity in w r hich the lungs rest. And the lungs, both on account of the work of their own muscles and of that of the greater amount of chest space in which they lie, become larger and more enduring. Thus, through deep breathing conducted as an ex- ercise, the lungs become larger, have more space in which to move and expand, and have furthermore a greater air capacity.
