Which of the following is NOT a component of physical fitness?

Body composition is indeed a component of physical fitness. It refers to the proportion of fat and non-fat mass in the body, and impacts overall health and fitness levels. The other components listed, such as muscular strength, flexibility, and cardiorespiratory fitness, are also integral parts of a well-rounded fitness program.

Muscular strength indicates the maximum amount of force a muscle or muscle group can exert, while flexibility involves the range of motion in joints and the ability to stretch muscles effectively. Cardiorespiratory fitness assesses the efficiency of the heart, lungs, and circulatory system in supporting physical activity. Each of these aspects contributes to overall health and fitness, illustrating the broad spectrum of physical fitness components beyond just body composition.
