Zone 2 Training: Why Slow Running Extends Your Life
What Is Zone 2 Training?
Zone 2 refers to a heart rate zone where you can hold a conversation but feel slightly challenged. For most people, this is 60-70% of max heart rate.
Why It Matters
Research from Dr. Inigo San Millan at the University of Colorado shows that Zone 2 training dramatically improves mitochondrial function.
