Frequently Asked Questions

Why Tanaka over 220 − age?
Tanaka 2001 (208 − 0.7 × age) was validated on 18,712 subjects, ±7bpm vs 220 − age which has ±15bpm error. Especially over-50: Fox formula underestimates HRmax by 10-15bpm.
What is Zone 2 exactly?
Aerobic base zone — 60-70% of HRmax (or 65-75% via Karvonen reserve method). Mostly fat-burning, mitochondrial-density-building, vagal-tone-improving. Talking test: full sentences without gasping.
Why is Zone 2 the longevity zone?
Mitochondrial biogenesis is most stimulated at Zone 2 intensity. Peter Attia / Iñigo San Millán research: 3-4 hr/week at Zone 2 = primary cardio prescription for healthspan, before HIIT. HIIT only adds value once Zone 2 base is built.
