Which component of physical fitness relates to the ability to stretch and move comfortably?

Flexibility is the component of physical fitness that refers to the ability to stretch and move comfortably. It encompasses the range of motion available in a joint or group of joints, contributing to overall movement efficiency and reducing the risk of injury. Increasing flexibility allows for smooth and controlled movements, enhancing performance in various physical activities. This can involve stretching various muscle groups to promote elasticity and improve posture, coordination, and balance. The other components listed—body composition, muscular strength, and cardiovascular efficiency—play distinct roles in overall fitness, but they do not directly address the capacity to stretch and move comfortably like flexibility does.
