Humans aren't the fastest animals on land — but we're among the best at going the distance. Our secret weapon? Efficient cooling through sweat and incredible endurance. This is why persistence hunting worked for our ancestors.
Key takeaway for training: While we can't match a cheetah's acceleration, humans have superior running economy and thermoregulation. Consistent training improves how efficiently your body uses oxygen and recycles energy through tendons and muscles.
Focus on building aerobic base and running economy — that's where real gains happen over months and years.
