Getting the proper amount of exercise is one of the most important elements to maintaining a healthy, happy lifestyle.
Only about "12% of students get the recommended amount of exercise for a healthy state of being...consider the benefits that a great workout can have on your smarts. Studies show that exercising doesn't just boost your health, it can also boost your intelligence and mental acuity. From elementary school all the way through college-level education, regular exercise is seen to improve test scores and even IQ levels. In fact, working out right before a test can aid in boosting performance."
