Principlev1
Prioritize moderate aerobic movement that elevates heart
Prioritize moderate aerobic movement that elevates heart rate for 10-30 minutes over athletic exhaustion, as BDNF elevation and neurotransmitter benefits have low thresholds but diminishing returns beyond moderate intensity.
Why This Is a Principle
Derives from Neural Plasticity Enables Lifelong Automatic Learning (neuroplasticity throughout life) and Expertise Through Deliberate Practice (expertise through deliberate practice). The lesson documents that BDNF and cognitive benefits appear at moderate intensity, not just extreme. The prescriptive principle: optimize for the threshold, not the maximum, when the goal is cognitive enhancement.
