How is physical fitness defined?

Physical fitness is fundamentally defined as the ability to perform daily tasks without undue fatigue. This definition emphasizes the importance of being able to engage in everyday activities, which can include a variety of physical demands such as lifting, walking, or performing household chores, without experiencing excessive exertion or tiredness.

The focus of this definition is on overall functional fitness and endurance that contributes to well-being and quality of life. It relates to how effectively a person can live their life on a day-to-day basis while maintaining a good level of energy and health.

The other definitions limit the scope of physical fitness to specific abilities, such as endurance in long-distance running or strength in lifting weights, which are important but do not encompass the broader concept of overall physical readiness and health that impacts daily living. Additionally, being free from physical exercise suggests a lack of engagement in activities that promote health and fitness, which contradicts the very essence of what it means to be physically fit.
