Health and fitness

The most widely accepted definition of good health is that of the World Health Organization Constitution. It states that "health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity" (World Health Organization, 1946).

The notion of physical fitness is used in two close meanings.
General fitnessIn its most general meaning, physical fitness is a general state of good physical health. A physically handicapped person's body may be physically fit (healthy), though its ability is likely to be less than optimum.
Physical fitness is usually a result of regular physical activity and proper nutrition.
Physical fitness is often divided into three types:
Cardiovascular endurance
Physical strength and endurance

The government Physical Activity Guidelines for Americans say to aim for at least 2 hours and 30 minutes of aerobic activity that requires moderate effort each week.

Task-oriented fitnessA person may be said to be physically fit to perform a particular task with a reasonable efficiency, for example, fit for military service.
Military-styleIn recent years, Military-style fitness training programs have become increasingly popular among civilians. Courses are available all over the United States and Europe.
They are usually taught by ex-military personnel. Very often the instructors held highly regarded positions within various military organizations. Often the instructors were formerly Drill instructors, Special Forces Operatives or held otherwise distinguished positions.

These courses always have some common elements. They often focus on military style calisthenics and group runs. The courses are often held very early in the morning and will meet in almost any weather. Students can expect push-ups, sit-ups, pullups, and jumping jacks, as well as more obscure drills such as flutter kicks, sun worshippers and flares. Almost invariably a workout will include short runs while longer runs are more scheduled. Special forces are renowned for their level of fitness and intensity of their workouts.
