Zone 2 Cardio
Zone 2 Aerobic Training (Low-Intensity Steady-State)
Sustained low-intensity aerobic exercise performed at 60-70% of maximum heart rate. Builds mitochondrial density, improves fat oxidation, and is considered by longevity researchers like Peter Attia to be the foundation of healthspan.
How Zone 2 Cardio Works
Zone 2 exercise targets the aerobic energy system, specifically Type I slow-twitch muscle fibers rich in mitochondria. Training at this intensity maximizes mitochondrial biogenesis via PGC-1α activation without crossing the lactate threshold.
📊 Evidence by Outcome
Strong evidence that regular Zone 2 training reduces cardiovascular mortality by 30-50%. Improves VO2 max, cardiac output, and arterial health.
60 studies • Consistency: High • Effect: Large
Zone 2 uniquely stimulates mitochondrial density and efficiency. Studies show 20-40% increases in mitochondrial content after 8-12 weeks of consistent training.
25 studies • Consistency: High • Effect: Large
Improves insulin sensitivity, blood glucose regulation, and shifts metabolism toward fat oxidation. Key for metabolic flexibility and weight management.
40 studies • Consistency: High • Effect: Moderate
Large epidemiological studies consistently show that regular moderate-intensity aerobic exercise reduces all-cause mortality by 25-40%.
50 studies • Consistency: High • Effect: Large
Regular aerobic exercise increases BDNF, hippocampal volume, and reduces dementia risk by 20-30%.
30 studies • Consistency: High • Effect: Moderate
