Research suggests regular aerobic exercise can boost the size of the hippocampus, the core of the brain’s learning and memory systems.

When you exercise your body releases a lot of good things, including brain-derived neurotrophic factor (BDNF), which is good for the health of brain cells.

The idea is that when you exercise you’re much more likely to cause the brain to make new brain cells.

This is backed up by a German study that showed how cycling while learning a foreign language helped people remember new words better.
