Fat tissue is composed of three different categories: essential fat, storage fat and non-essential fat

Physical fitness is one of the most important aspects of life. It is the body’s primary source of strength and energy.  It is also the spring of good mood, confidence and sense of well-being.  It makes up more than one-half of what we need to make us perform our roles in our endeavors of life.

Whether you are at work, at play or just simply spending your time leisurely, you need to be fit.  Even if you are trying to rest, you can never relax if you are bothered by a discomfort or achy sensation in any part of your body.

You need to stay fit in order to enjoy the best of yourself.  Here are some of the most important elements of fitness that you should know:

1.  Cardiovascular Fitness

It refers to the health of your heart, blood, blood vessels, and respiratory system as well as their ability to maintain sufficient supply of oxygen and fuel to give your body the energy it needs.

There are two ways to improve your cardiovascular fitness.  One of them is by doing aerobic exercises.  This exercise requires oxygen which needs to be sustained for extended periods.  Examples of aerobic exercises include jogging, swimming, cycling and other forms of physical activity that raises your heart rate for long periods.

The second method of improving cardiovascular fitness is by doing anaerobic exercises.  This type of exercise does not require oxygen and cannot be sustained for periods longer than one and a half minutes.

This exercise requires you to go at a very fast rate and you will not be able to maintain that pace for long.  Examples of anaerobic exercises include 200-meter dash and 50-yard swimming exercises.

2. Muscular Endurance

Muscular endurance refers to your body’s ability to perform a certain movement repetitively for a long time.  It is one of the first things that you need to develop in order to get used to exercise.  Being able to do 50 push-ups or more at one time is a good example of muscular endurance.

3. Muscular Strength

Muscular strength refers to your muscular ability to lift weights at any given time.  Muscular endurance and muscular strength are two different things.

Unlike muscular endurance, muscular strength does not require you to perform a physical activity for a long time as it only needs a short amount of time to accomplish.

This aspect of fitness actually requires you to develop the ability to lift weights.  But you need to have a strong muscle base in order to obtain muscle strength, and you can do it by doing muscle endurance exercises which help to build strength and muscle mass for you.

4. Flexibility

Flexibility refers to your body’s ability to move its joints smoothly through a complete range of motions.  It is one of the most important components of fitness.  Everyone needs to have a certain amount of flexibility in order to live a functional, injury-free life.

Flexibility is necessary in almost all of your physical activities.  You even need it to perform simple tasks such as tying your shoes or wearing your shirt.  Lack of flexibility can restrict your movement.

You can improve your flexibility by performing static exercises everyday.  You can do it by moving your muscles to their stretching point and holding on to that stretched position for a designated amount of time.

5. Body Composition

Body composition refers to the ratio of fat to muscle, bone, and other tissues that make up your body.  It is often expressed as the ratio of lean mass to fatty mass.

Lean tissues includes muscle, bone, skin, internal organs and body water while fatty tissues is composed of essential fat, storage fat and non-essential fat.

A good body composition is necessary because it can help a person develop self confidence, a sense of well-being and a good self-image.
