Practice diaphragmatic breathing by inhaling deeply through your nose, allowing your diaphragm to expand fully.
Inhale through your nose for two counts, then exhale through pursed lips for four counts. Pursed-lip breathing helps regulate airflow, slows down breathing, and improves the efficiency of oxygen exchange in the lungs.
Use a spirometer, a device that measures the volume of inhaled and exhaled air. Perform deep inhalations and exhalations to reach and surpass your normal lung capacity.
IHT involves short periods of breathing air with reduced oxygen levels. This can be achieved using altitude training masks or by practicing breath-holding exercises.
Engage in aerobic activities like running, swimming, cycling, or brisk walking. These exercises increase demand on the respiratory system, enhancing lung capacity over time.
