But it's important for people to fit movement into their lives because a growing body of research is showing the positive effects that physical activity can have on your brain. Our guests Sarah Lose and Max Gaitan, research specialists and exercise physiologists, discuss building cognitive resilience, defining physical activity, and researching exercise and its links with brain health.
