Zone 2 Cardio Explained: The Longevity Exercise Most People Skip

Most people doing cardio are working at the wrong intensity — too hard to trigger the metabolic changes that matter most for longevity. Zone 2 heart rate training is the exercise prescription most adults over 50 have never heard of, and the science behind it is compelling.

In this video, you'll learn:

• What Zone 2 is: 60–70% of max heart rate, the conversational pace where fat is the primary fuel
• How to find your Zone 2: use the 180-minus-age formula (120 bpm upper ceiling for a 60-year-old)
• Why it works: Zone 2 triggers mitochondrial biogenesis via PGC-1α — the most potent non-pharmacological longevity pathway known
• The VO2 max mortality finding: low cardiorespiratory fitness is a stronger mortality predictor than smoking or diabetes
• The Copenhagen City Heart Study: moderate-pace jogging added over 6 years of life expectancy
• Why Zone 3 is wasting your cardio time and what to do instead
• The optimal dose: 150–180 minutes per week minimum, 3–4 hours for longevity
• Best low-impact Zone 2 activities for adults over 50 with joint sensitivity

Zone 2 feels almost embarrassingly easy. That's exactly why most people skip it — and exactly why it works.
