Expert Positions
The Verdict
All 5 experts recommend Zone 2 exercise for longevity. Attia is the clear authority with 30+ dedicated videos and a close collaboration with Dr. Inigo San-Millan — he considers Zone 2 one of his four pillars of exercise for the Centenarian Decathlon. Huberman targets 200 minutes per week. All experts pair Zone 2 with higher-intensity training (HIIT/Zone 5) and agree mitochondrial health is the core mechanism.
Where They Disagree
Patrick's guest Dr. Martin Gibala presents data showing HIIT can yield similar VO2 max improvements as Zone 2 in much less time — a time-efficiency argument that somewhat challenges Attia's heavy Zone 2 volume prescription.
Weekly volume differs: Attia targets 3-4 hours of pure Zone 2, Huberman targets 200 minutes, Hyman suggests 150-200 minutes. Johnson combines Zones 2-4 for a 4.5-hour weekly target, making direct comparison difficult.
