Fitness Fact of the Day: Exercise Boosts Brain Power

Not only does exercise improve your body, it helps your mental function, says certified trainer David Atkinson.

"Exercise increases energy levels and increases serotonin in the brain, which leads to improved mental clarity," says Atkinson, director of program development for Cooper Ventures, a division of the Cooper Aerobics Center in Dallas.

All that makes for a more productive day.

"It is clear that those who are active and who exercise are much more productive at work," says Todd A. Astorino, assistant professor of kinesiology at California State University-San Marcos.

Improved productivity not only makes you a better worker, it makes things better for everyone in the workplace (or home). 

Do you find this to be true?  Do you have more energy when you exercise?  Are you in a better mood?  What are some of the positive effects exercise has had for you over the past 21 days?
