In the definition of physical health it can be stated that "it is an important part of the overall well-being of a person. It includes fitness, agility, cardiovascular condition, endurance, muscular strength etc."
It is a state of complete well-being in which a person is totally fit to perform his daily routine activities without any hindrance. This description is very broad and covers every aspect of outward activities by our body and also perfect performance of our internal organs.
Our outward activities like, walking, running, seeing, hearing etc. must be fine tuned and normal. Our internal organ systems and their activities must be perfect and normal in a state of fitness.
Hence another definition of physical health may be stated as "a way to maintain our well-being and fitness with activities which enhance our overall well-being by sufficient exercise and right type of nutrition."
