The Pocket Guide to Breathing

Most runners never think about their breathing—until it lets them down. Your legs feel strong, but your chest is tight, your shoulders are tense, and your heart rate is climbing faster than your pace. The problem isn't always fitness. It's often your breathing. This practical, science-based guide is here to change that. Breathing is automatic, but performance isn't. When you learn to breathe with intention, you unlock more endurance, more control, and more enjoyment in every run, walk, or workout. The Pocket Guide to Breathing is designed for everyday athletes, recreational movers, and performance-focused runners who want to run calmer, go further, and recover faster. Inside, you'll learn: ? Why breathing is often the hidden bottleneck in endurance performance ? How your heart, lungs, and muscles form one powerful oxygen delivery loop ? Simple breathing techniques that can be applied on your very next run ? Cadence-based breathing to stabilize rhythm and regulate effort ?
