The book is structured in three parts, beginning with the anatomy and physiology of the respiratory system, then identifying factors influencing respiratory health, and finally focusing on practical strategies for improving lung strength.
While some decline in lung function is inevitable, Lung Strength argues that proactive lifestyle interventions, such as breathing exercises and physical training designed to enhance respiratory muscle strength, can significantly slow this process. The book provides a science-based program, drawing from studies employing spirometry and gas exchange analysis, to help readers optimize their respiratory health at any stage of life.
