Exercise doesn’t just strengthen your body—it powers up your brain too. Dr. David Merrill, director of PNI’s Brain Health Center, explains that physical activity boosts brain-derived neurotrophic factor (BDNF), a protein that helps neurons grow and connect, supporting learning and memory. While BDNF isn’t available in a pill, exercise naturally increases its levels, promoting brain plasticity and resilience. Regular workouts keep your brain sharp and adaptable, especially as you age.
