Aerobic cardio training
Evidence grade: Essential
Sustained rhythmic exercise—like walking, cycling, swimming, or running—that raises heart rate and breathing while using oxygen efficiently for energy production.

How to practice Aerobic cardio training
Accumulate 150–300 minutes per week of moderate (e.g., zone 2 heart rate) or 75–150 minutes of vigorous aerobic activity (e.g., zone 3+). Include a mix of continuous sessions (30–60 minutes) and interval-based efforts for variety. Monitor intensity with the “talk test” or target 60–80% of maximum heart rate. Consistency across months yields the strongest brain benefits.
The evidence behind Aerobic cardio training
Aerobic exercise enhances cerebral blood flow, increases hippocampal volume, and boosts BDNF, which drives neurogenesis and synaptic plasticity. Dozens of RCTs show aerobic training improves memory, processing speed, and mood while lowering dementia and depression risk. Mechanism is primarily vascular and neurotrophic. Evidence is strong, consistent, and dose-responsive.
