What is flexibility?

Flexibility refers specifically to the capacity of a joint or muscle to move through its full range of motion. This encompasses the ability of muscles, tendons, and ligaments to elongate and allow movement at the joints without restriction. Increased flexibility can enhance overall physical performance, reduce the risk of injury, and improve posture and alignment.

This understanding of flexibility is vital in various contexts, such as during physical activity or rehabilitation, as it plays a significant role in facilitating movement and overall functionality. By promoting a full range of motion, flexibility contributes not only to athletic performance but also to day-to-day activities, enabling a person to move more freely and efficiently.

In contrast, the other options describe different aspects of physical fitness or performance. For instance, producing maximum effort relates to strength or power, while performing aerobic exercises without fatigue pertains to endurance. The capacity of a muscle to withstand stress relates more to strength and resilience than to flexibility itself. Therefore, the definition of flexibility being the range of motion around joints is distinct and accurately captured in the correct choice.
