The five components of physical fitness are

• 
  
• 
  
• 
  
• Muscle strength
• Cardiovascular endurance
• Body composition
• Muscle endurance
• Flexibility

         1. Muscle Strength

Muscle strength refers to the amount of force a muscle can exert, in a single effort. Exercises like the bench press, leg press or bicep curl might be used to measure muscle strength.

            2.Cardiovascular Endurance

Cardiovascular endurance refers to the ability of your heart and lungs to work together to fuel your body with oxygen. The Cooper Run is most often used to test cardiovascular endurance. Aerobic conditioning, like jogging, swimming and cycling, can help improve cardiovascular endurance.

        3. Body Composition

Body composition refers to the amount of body fat you have, versus the amount of lean muscles, bones and organs. There are several tests that can be used to measure body composition. The most reliable is underwater weighing, but due to the size and expense of the equipment, this type of test isn't common. Many doctors,gyms and health clubs use a pinch test instead.

        4. Muscle Endurance

Muscle endurance refers to the ability of a muscle to perform a continuous effort without fatiguing. Cycling, step machines and sit up tests are often used to measure muscular endurance.

   5. Flexibility

Flexibility refers to the ability of each joint to express its full range of motion. Flexibility can be tested by stretching individual muscles or by performing exercises such as the lunge or the sit and reach.
