Most experts agree there are five basic components of fitness. Include them in your workouts.
1) Aerobic Endurance- Your level of aerobic endurance measures your ability to do moderately strenuous activity over a period of time. It’s a measurement of how efficiently your heart and lungs work together to supply oxygen to your body during exertion and exercise. This fitness component is also called aerobic fitness.
2) Muscular Endurance- Muscular Endurance measures your fitness level by your ability to hold a particular position for a sustained period of time or repeat a movement many times. One example might be to lift a five-pound weight 20 consecutive times.
3) Muscular Strength- The ability to exert maximum force. It is possible to have greater muscular strength in one area, than another. For example, you may have great strength in your arms, while lacking strength in your legs. One example might be lifting the heaviest weight you can possibly lift.
4) Flexibility- Flexibility fitness measures the ability to move a joint through its full range of motion or the elasticity of the muscle. This is how limber you are.
5) Body Composition- This fitness area measures the proportion of fat in your body as compared to your bone and muscle. It does not refer to your weight in pounds or your shape.
