The New York Times reports on a new study that had rats try three different kinds of workouts:
- Aerobic: running on a treadmill or wheel
- Resistance: climbing on a wall with weights attached, to simulate weight training
- High Intensity Training (HIT): running very fast, interrupted with periods of not doing that
They then measured how many new brain cells appeared after seven weeks of the routine, and found out that from most to least by group, it was aerobic, HIT, and then resistance — with the resistance group basically having no new brain cells. The HIT group had some, but not nearly as much as the aerobic group. Moral of the story: jogging makes you smarter.
