What does flexibility in physical fitness refer to?

Flexibility in physical fitness specifically refers to the range of motion available at a joint. This encompasses how far a joint can move in different directions, which is essential for overall mobility and functional movement. Improved flexibility can lead to better performance in physical activities, reduced risk of injury, and enhanced recovery after exercise. While stretching one's muscles might contribute to improving flexibility, it is not an all-encompassing definition. Other options like strength and endurance pertain to different aspects of fitness and do not relate directly to flexibility. Therefore, understanding flexibility as the range of motion provides a precise and accurate definition within the context of physical fitness.
