This study suggests the brain benefits of moving more may be largest for people starting from very little activity.
Middle-aged and older adults who moved more had healthier-looking brain wiring on MRI scans, but the benefit wasn't the same for everyone. The gains were biggest in people who were older or barely active, and they leveled off at higher activity levels. Part of the link ran through body weight, heart and metabolic health, and inflammation. This was a snapshot in time, so it can't prove exercise caused the healthier brains.
