your heart is a pump, when you exercise your heart pumps harder and faster, your legs create a flowing motion that helps the blood make it back to the heart. during all this the brain experiences a surge in blood levels, oxygen, metabolic exchanges happen faster and so your brain is more effective. add into that, the body breaks down fats to power you, those fats have omega fatty acids that are released into the blood stream and go to the brain to provide nutrients. this is why drinking coffee wakes you up. what I really want is a pair of those leg pumps that assist the heart, so I can sit on my ass longer and code whilst getting the benefits of exercise on my brain :)
