Fitness is defined as the ability of the body to carry out various types of daily activities without feeling tired.
Physical fitness is measured on the basis of some devices, and many scientific tests, and then compared to the ideal level of fitness, and determined the ability of the individual, and fitness efficiency.
Fitness is divided into two parts:
1. General fitness, which refers to health and well-being, and special fitness, which relates to a particular type of exercise.
2. Good fitness can be obtained by getting proper nutrition and taking
Physical fitness provides strong bones and muscles, leads to better health and well-being, prevents various health problems, reduces the risk of several diseases like blood pressure, diabetes, cancer, etc. and improves a better quality of life.
Physical fitness reduces stress, tension and chances of being depressed and makes you feel better.
You can improve your physical fitness and body composition
The Elements of Physical Fitness
Elements of fitness are all the components or characteristics that play an important and significant role in learning the exercise techniques and achieving sound health (such as strength, speed, elongation, agility, flexibility ..... etc) and all the qualities that result from the merger of two or more of them.
Determining the elements of physical fitness varied from school to school and from one scientist to another according to their views, but most of them agreed on some basic fitness elements, and we have addressed some of them here.

Muscle Strength
Muscle strength can be defined as the ability of a muscle to exert as much energy as possible.
There are a number of factors that affect muscle strength; such as muscle size, number, and type of fibers, and elasticity, in addition to psychological factors.

Body Composition
Body composition is the ratio of fat mass to fat-free mass in the body, and muscles, bones, cartilage, and other vital parts of the body are part of the fat-free mass.

Speed Fitness
Speed is the element that indicates the time a muscle needs to exert the required physical effort and is affected by many factors; such as muscle fibers, strength, and elasticity, as well as a strong will, and nervous compatibility.

Balance and Coordination
Balance indicates the body's ability to resist falling as long as possible. It is influenced by the integrity of the body's organs, its equilibrium base, its high center of gravity, as well as the Earth's gravity line, and psychological factors.

Flexibility
Flexibility expresses an individual's ability to perform activities to the greatest extent that a muscle allows. It is affected by the mobility of the joints well, the elasticity of the muscle. Continuous and regular training has an effect on muscle flexibility.

Agility
Agility is the ability of an individual to change the direction of his body, whether on the ground or in the air, in the shortest possible time.
The body's agility is influenced by many factors; the most important are: the integrity of the nervous system, muscle capacity, as well as the type of activity, and the speed of the body's response to it.


Cardiovascular Endurance
Endurance is the expression of the ability of the body and its muscles to the possibility of fatigue and stress while exercising a certain physical activity. This is an important element of fitness and must be available to those who work in conditions that require long and arduous hours of work.
Controlling blood pressure
Physical fitness has proven to support the body's blood pressure. Staying active and exercising regularly builds a stronger heart. The heart is the main organ in charge of systolic blood pressure and diastolic blood pressure. Engaging in a physical activity raises blood pressure. Once the subject stops the activity, the blood pressure returns to normal. The more physical activity, the easier this process becomes, resulting in a fitter cardiovascular profile.[31] Through regular physical fitness, it becomes easier to create a rise in blood pressure. This lowers the force on the arteries, and lowers the overall blood pressure.[32]

Cancer prevention Edit
Centers for disease control and prevention provide lifestyle guidelines for maintaining a balanced diet and engaging in physical activity to reduce the risk of disease. The WCRF/ American Institute for Cancer Research (AICR) published a list of recommendations that reflect the evidence they have found through consistency in fitness and dietary factors that directly relate to cancer prevention.

The WCRF/AICR recommendations include the following:

Be as lean as possible without becoming underweight.
Each week, adults should engage in at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity physical activity.
Children should engage in at least one hour of moderate or vigorous physical activity each week.
Be physically active for at least thirty minute
