Zone 2 Cardio with Nasal Breathing

What is Zone 2 Cardio with Nasal Breathing?

Low-intensity cardio where you can maintain a conversation, done exclusively through the nose. Zone 2 (60-70% max HR) builds mitochondrial density, improves fat oxidation, and is considered the #1 exercise for longevity by Peter Attia and the r/Biohacking community. Nasal breathing acts as a natural intensity governor and adds its own cognitive benefits (BDNF release, better oxygen delivery).

Is there evidence for it?
