Stop reading this right now and go for a walk.
It’s that simple.
Exercise Powers the Body — and the Mind
They used to say you don’t grow new brain cells. They were wrong.
What really feeds those baby brain cells? Hitting the gym.
A three-month exercise regimen increased blood flow to the part of your brain focused on memory and learning by 30%.
The Dumb Jock Is a Myth
Being in good shape increases your ability to learn. After exercise, people pick up new vocabulary words 20% faster.
Indeed, in a 2007 study of humans, German researchers found that people learn vocabulary words 20% faster following exercise than they did before exercise, and that the rate of learning correlated directly with levels of BDNF.
Want to be more creative? Sweating for about a half hour on the treadmill notably increases cognitive flexibility.
Fine, you can see differences on an MRI and with nerdy tests. Does it make a difference in the real world?
Office workers who exercised at lunch were more productive, less stressed and had more energy.
That super-productive co-worker who runs every day might not exercise because he has energy — he might have energy because he exercises.
Sweating Increases Smiling
Can’t make it simpler than this: Research from Duke University shows exercise is as effective as antidepressants in treating depression.
It also reduces anxiety.
What if you’re not depressed or anxious? Stay sedentary and you’re 1.5 times more likely to eventually become depressed.
Still not convinced? People who exercise are, across the board, mentally healthier: less depression, anger, stress and distrust.

What’s optimal? Exercise six days a week, 45 minutes to an hour per day.
Stop rolling your eyes. It’s not all or nothing.

Here’s something proved to make you smarter, healthier and happier. What could be a better investment of your time?
You might ask: If it’s obviously so great, why don’t we all do it?
And, in general, we don’t do what makes us happy — we do what’s easy.
But it doesn’t have to be that way.
