Just as exercise makes the bones, muscles, heart, and lungs stronger, researchers think that it also strengthens important parts of the brain. Research suggests that aerobic exercise helps you learn new things and remember old information better. Aerobic exercise sends more blood to the brain and it feeds the brain with substances that develop new nerve connections. If the exercise has complicated movements like dance steps or basketball moves, the brain produces even more nerve connections. The more connections, the better the brain can process all kinds of information.
