Which of the following is a component of physical fitness?

Flexibility is one of the key components of physical fitness, and it refers to the range of motion available at a joint or group of joints. This aspect of fitness plays an essential role in overall physical performance, as increased flexibility can enhance athletic abilities, reduce the risk of injuries, and improve posture and coordination. Flexibility is often developed through regular stretching exercises, which can promote muscle elasticity and joint mobility, contributing significantly to an individual’s functional capacity in daily activities and sports.

In contrast, while nutrition, mindset, and sociability can positively influence a person's overall health and ability to engage in physical activities, they do not directly fall under the traditional categories of physical fitness components, which typically include cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition.
