What you’ll learn
- Explain how exercise increases neurotrophic factors and promotes neurogenesis
- Understand the cognitive benefits of aerobic exercise
- Apply exercise science to optimize brain health an academic performance
When you exercise, your muscles produce chemical signals including BDNF (Brain-Derived Neurotrophic Factor). BDNF promotes neurogenesis—the growth of new neurons in the hippocampus, the brain region critical for learning.
A 2025 meta-analysis found that aerobic exercise had the greatest impact on adolescent cognitive function, particularly for executive function and attention. Kids with 'fit' brains showed more efficiently organized brain networks.
You don't need to be an athlete. Moderate-intensity aerobic exercise for 60 minutes per week shows measurable benefits. You're building a faster, smarter, more resilient brain that will serve you throughout your life.

Takeaways
- Exercise triggers BDNF production and neurogenesis, growing new brain cells
- Aerobic exercise has the strongest cognitive benefits for attention and memory
- 60 minutes per week of activity reorganizes your brain for better efficiency
