the category "activity" includes exercise, rest and sleep. there is much confusion about the role that exercise and sleep play in health. like diet, activity is an area where each person can take control.    

vigorous physical activity puts demands on all body systems to work harder. the body responds to these demands by becoming stronger and more efficient. the health benefits of exercise include improved metabolism, increased muscle and bone strength, more efficient cardiovascular (heart and blood vessel) function, larger lung capacity, tension reduction, and improved sleep.

the most efficient way to obtain these benefits is through regular aerobic exercise. aerobic exercise involves the large muscles of the body, particularly the legs. examples include brisk walking, jogging, swimming and bike riding. exercise is most enjoyable when it is incorporated into recreation and becomes a regular part of your normal daily activities.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
