What does flexibility primarily refer to in fitness?

Flexibility primarily refers to the ability to move joints freely through their full range of motion. This concept is crucial in fitness because it directly impacts overall mobility, athletic performance, and injury prevention. Adequate flexibility allows individuals to perform movements efficiently and safely, whether it’s during exercise or daily activities. For instance, activities like yoga and stretching routines specifically target flexibility to enhance muscle elasticity and joint support.

In contrasting contexts, maintaining balance involves stabilizing the body during movement but does not directly relate to how well you can move your joints through a full range. Lifting heavier weights focuses on strength and muscular endurance, while running long distances pertains to cardiovascular fitness. Thus, these options highlight other important fitness components but do not capture the essence of flexibility as related to joint mobility.
