A Definition of Fitness

Physical fitness defines a state of total health and well being and, more importantly, the capacity to do regular aspects of daily activities and sports without any restriction. Physical fitness may be defined as the capacity for vigorous or gentle movement without pain, restriction or limitation. Physical fitness is usually achieved through physical activity, proper nutrition, adequate rest and moderate-to-varying sleep.


Muscles and fibers are stretched and broke down while we engage in physical activity. Therefore, to improve fitness, the muscle tissues and fibers must be kept in good shape and capable of sustained tension. Muscle strength and endurance can be improved by stretching, breaking down and rebuilding muscle tissue through resistance exercises. Some muscle groups are particularly important for sports performance, including endurance, flexibility, power, endurance and strength. The larger muscles such as the legs, back, abdominals, upper body, hips and glutes, as well as the smaller muscles such as the biceps, forearms, calves, and hamstrings, support and stabilize the body while performing different types of activities.

In general, it is the quality of your breathing, which makes up a major factor in the definition of your fitness level. Healthy lungs maintain healthy blood circulation. Other important factors in the definition of fitness include your well-developed muscular endurance, flexibility, cardiovascular endurance, muscular mass, muscular strength, muscular coordination, bone mineral density, muscle responsiveness and the level of your well-being. Your well-being is defined by how you perceive and experience your physical health.

Physical fitness means different things to different people. To some, it is merely reaching a certain physical goal. To others, it is maintaining a specific level of fitness over a period of time. For many people, exercising regularly and maintaining a certain level of fitness mean achieving the highest level possible. For others, physical fitness means being able to perform an activity that involves using the upper extremities of the body.

The definition of fitness also includes the way you think and feel when you are engaged in a physical activity. Healthy fitness means being mentally and emotionally prepared to do whatever it takes to achieve your goals. For some people, being physically fit simply means the ability to move around comfortably and without pain. For others, fitness means being capable of doing difficult activities without tiring or suffering from any injury.

Fitness is a necessary part of life. Whether you need to lose weight, build muscles, become more limber, improve your golf game, or reduce your risk of developing a disease, maintaining a good level of fitness can have many benefits for your mental and physical health. Maintaining a regular exercise routine and working out regularly can help you improve your mental fitness, while being physically fit can increase your overall health. Whether you are trying to lose weight, build muscle, or improve your golf game, fitness makes a difference.
