Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities.
Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest.
Before the industrial revolution, this was defined as the capacity to carry out the day’s activities without undue fatigue.
However, with automation and changes in lifestyles 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.
This is defined as the quality or state of being fit. Around 1950, perhaps consistent with the Industrial Revolution and the treatise of World War II, the term “fitness” increased in western vernacular by a factor of ten.
The modern definition of describes either a person or machine’s ability to perform a specific function or a holistic definition of human adaptability to cope with various situations.
This has led to an interrelation of human fitness and attractiveness that has mobilized global fitness and fitness equipment industries.
A well-rounded program improves a person in all aspects of fitness compared to practicing only one, such as only cardio/respiratory endurance or only weight training.
A comprehensive program tailored to an individual typically focuses on one or more specific skills, and on age- or health-related needs such as bone health.
