history: Im a sports man ,Physical fitness is regular stuff I do to keep fit. Oh, yeah? Generally physical fitness can be had by good nutrition, exercise and rest. What steps do I need to take to keep my body in shape? I honestly don't know, though I can tell you that fitness is the state of being fit. So what type of  food do I need to eat regularly?
knowledge: However, with automation and changes in lifestyles ''physical fitness'' is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
