About fitness

Physical fitness comprises two related concepts:
1)General fitness (a state of health and well-being) and specific fitness (a task-oriented definition based on the ability to perform specific aspects of sports or occupations).
2)Physical fitness is generally achieved through correct nutrition, exercise, and enough rest.

In previous years[when?], fitness was commonly defined as the capacity to carry out the day’s activities without undue fatigue. However, as automation increased leisure time, changes in lifestyles following the industrial revolution rendered this definition insufficient.[citation needed] These days, physical fitness is 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.

Components of physical fitness
The President's Council on Physical Fitness and Sports—a study group sponsored by the government of the United States—declines to offer a simple definition of physical fitness. Instead, it developed the following chart:[1]
