Aerobic intensity and hippocampal gains

Neuroscientist Dr. Tommy Wood breaks down what it actually takes to keep your brain sharp as you age. Drawing from his new book The Stimulated Mind, Tommy makes the case that movement is non-negotiable for brain health — and that even small amounts make a meaningful difference. From walking and resistance training to dancing and pickleball, different types of exercise protect different parts of the brain in ways that compound over time. The bottom line? You don't need a perfect plan. You just need to start.
