What Is Physical Fitness?

Physical Fitness consists of five basic components which involve the heart, lungs, strength, endurance, and flexibility.

1. Cardiorespiratory or “Cardio”

The ability to do moderately strenuous activity over a period of time. It reflects how well your heart and lungs work together to supply oxygen to your body during exertion and exercise.

2. Muscular Endurance

The ability to hold a particular position for a sustained period of time or repeat a movement many times. An example of this would be performing a particular exercise 20 to 30 times consecutively without stopping.

3. Muscular Strength

The ability to exert maximum force, such as lifting the heaviest weight one time. It is possible to have muscular strength in one area, say your arms, while lacking strength in another area, such as your legs. Find that happy medium.

4. Flexibility

The ability to move a joint through its full range of motion; the elasticity of the muscle. This is how limber or supple you are.

5. Body Composition

The proportion of fat in your body compared to your bone and muscle. It does not refer to your weight in pounds or your figure.
