Passive flexibility refers to the range of motion achieved through the application of an external force, which may come from an external mechanism (like a partner or a piece of equipment) or the force of gravity. In this type of flexibility, the individual does not have to exert any muscular effort to stretch, allowing for a greater range of motion compared to when using only their own muscular capabilities.

This concept stands in contrast to other types of flexibility. For example, dynamic flexibility involves the active movements and muscle contractions that enable the joints to move through their full range of motion while engaging in physical activity. Active flexibility requires the muscles to contract to achieve a specific range of motion without assistance, which limits the extent compared to passive flexibility. Static flexibility, on the other hand, typically refers to the ability to maintain a stretch position but does not inherently specify whether it is assisted or unassisted, making it less precise than passive flexibility in this context.

Overall, passive flexibility distinctly identifies the role of external forces in achieving a greater range of motion, making it a crucial element in understanding flexibility training and rehabilitation.
