What is the term for the ability to move body parts through their full range of motions?

Flexibility refers to the ability of a joint or series of joints to move through an unrestricted, pain-free range of motion. It is an essential aspect of overall physical fitness, impacting not only athletic performance but also daily activities and injury prevention. A higher level of flexibility allows individuals to perform movements more effectively and with a lower risk of strains or injuries.

In contrast, body composition relates to the ratio of fat mass to lean mass in the body, which is a different measure of physical fitness. Muscular strength focuses on the amount of force a muscle can exert in a single effort, while aerobic exercise describes activities that improve cardiovascular endurance by increasing the efficiency of the heart and lungs. Thus, flexibility is the most appropriate term for the ability to move body parts freely through their full range of motion.
