Zone 2 Cardio for Longevity
Zone 2 training (heart rate 60–70% max) increases mitochondrial density and recovery speed, the foundation of endurance.
Why it matters: It’s the fitness base used by athletes and longevity experts. Too many lifters neglect heart health while chasing muscle.
Actionable steps:
- Perform 3x 30-minute sessions weekly.
- Keep pace where you can breathe easily but sweat steadily.
- Track HR zones with a smartwatch.
Takeaway: Strong hearts outlive strong egos.
