Strong Legs, Strong Mind: What a Twin Study Reveals About Brain Aging
When we think about protecting our brain as we age, most people think about puzzles, supplements, or memory training. But what if one of the strongest predictors of brain health isn’t in your head at all? A fascinating long-term twin study found that individuals with greater leg strength experienced better cognitive aging over time. Even when genetics were controlled for, the twin with stronger legs tended to show better cognitive function years later.cInterestingly, this wasn’t just reflected in performance. The study also found differences in brain structure, with greater leg strength associated with higher grey matter volume over time. This shifts the conversation in an important way. Brain health is not just about the brain. It’s about the body that supports it. (The study followed over...
