Which of the following is NOT a component of fitness?

Body strength is not typically classified as a discrete component of fitness; rather, the terminology used often refers to it as muscular strength or muscular endurance. The four primary components of fitness that are generally recognized include cardiovascular endurance, muscular endurance, flexibility, and body composition.

Cardiovascular endurance involves the ability of the heart and lungs to supply oxygen during sustained physical activity, while muscular endurance refers to the ability of a muscle or group of muscles to perform repeated contractions over time. Flexibility is the range of motion available at a joint. Body strength, while it reflects an important aspect of physical fitness, is usually merged into the broader categories of strength or muscular fitness rather than standing alone as a separate component.
