Answer:
1. Muscular Strength
This is the “power” that helps you to lift and carry heavy objects. Without muscular strength, your body would be weak and unable to keep up with the demands placed upon it. The way to increase strength is to train with heavy weights, working in the 4 – 6 or 12 – 15 rep ranges. The heavier the weight, the fewer reps you should perform!
2. Muscular Endurance
Endurance is the ability of your muscles to perform contractions for extended periods of time. Rather than just lifting or carrying something for a few seconds, the muscles are used for minutes. The way to increase strength is to train with light weights, working in the 20 – 25 rep range. Working with lighter weight will train the muscle fibers needed for muscular endurance, and the higher rep range leads to a longer period of exercise.
3. Cardiovascular Endurance
Cardiovascular endurance is your body’s ability to keep up with exercise like running, jogging, swimming, cycling, and anything that forces your cardiovascular system (lungs, heart, blood vessels) to work for extended periods of time.
4. Flexibility
Flexibility is one of the most important, yet often overlooked, components of physical fitness. Without flexibility, the muscles and joints would grow stiff and movement would be limited. Flexibility training ensures that your body can move through its entire range of motion without pain or stiffness.
5. Body Fat Composition
Body fat composition refers to the amount of fat on your body. For example, a 100-pound person with a 25% body fat composition will have a lean body mass of 75 pounds.
