Nasal Breathing During Exercise
Nasal breathing during exercise warms air and may build CO₂ tolerance on easy efforts. Use it on zone 2 work first; mouth breathing is fine at high intensity.
Nasal breathing during exercise filters and warms air, may improve CO₂ tolerance, and encourages diaphragmatic patterns—best introduced on easy zone 2 efforts before hard intervals. Switch to mouth breathing when intensity demands it without guilt.
Allergies or deviated septum may limit feasibility.
