Zone 2 Cardio

What it is

• Sustained low-intensity aerobic work at the top of fat-oxidation zone (conversational pace; ~60–70% max HR) — includes the Zone 2 walk.

How it works

• Drives mitochondrial biogenesis and fat-oxidation capacity (the same Mitochondrial Bioenergetics axis MOTS-C targets — they’re synergistic).

Goal relevance

• Foundational metabolic-health/longevity work and fat loss; pairs with mitochondrial peptides.

How to do it

• ~150–180+ min/week across sessions of 30–60 min.

Cautions

• Low-risk; build volume gradually.
