Lesson Overview

13.7 – Co₂ Tolerance Testing and Improvement: Carbon dioxide tolerance shows how well your body handles the urge to breathe harder during effort. Low tolerance can cause early breathlessness and stress during exercise. Simple breath holds can test your current level and guide improvements. Training CO₂ tolerance helps your body stay calm when levels rise, improving control and endurance. Practicing slow exhales or paced breathing builds confidence and reduces panic during tough moments. Stronger tolerance supports better oxygen use and more efficient performance. Progress feels empowering as your capacity grows. CO₂ training becomes a valuable skill that helps you stay smooth and composed when exercise intensity rises.
