Physical fitness is to the human body what fine tuning is to an engine. It enables us to perform up to our potential. Fitness can be described as a condition that helps us look, feel and do our best. more specifically, it is:
“The ability to perform daily tasks vigorously and alertly, with energy left over for enjoying leisure-time activities and meeting emergency demands. It is the ability to endure, to bear up, to withstand stress, to carry on in circumstances where an unfit person could not continue, and is a major basis for good health and well-being.”
Physical fitness involves the performance of the heart and the lungs, and the muscles of the body. And since, what we do with our body also affects we can do with our mind, fitness influence to some degree qualities such as mental alertness and emotional stability.
