A recent study found that among adults between ages 18 and 45, those who reported the most weekly aerobic exercise also had the most gray matter in the hippocampus, a brain region critical to memory. While studies have shown that exercise can increase hippocampal volume in children and older adults, this is one of the first to suggest that it may also have a positive effect in midlife, when brain volume is typically more stable.
