Fitness is a term that is used to help define the ability to stay in the best physical shape. You may ask, then, “What am I staying in shape for?” To each person, this will be something different.
For most, it is a matter of staying healthy as long as possible. You see, your body is designed to work as a machine. When each part of the machine is cared for, the entire machine works the best that it can. When the machine is neglected either in part or in the whole, then the machine won’t run well and eventually won’t run at all.
