Which statement defines flexibility?

Which statement defines flexibility?

• A. The range of motion of your joints, or the ability of your joints to move freely; mobility of muscles.
• B. The endurance of muscles under repeated contractions.
• C. The ability to generate maximal force quickly.
• D. The heart and lungs delivering oxygen to muscles.

Answer: (A)

Flexibility is the ability of a joint to move through its full range of motion. The statement describes the range of motion of your joints and the ability for them to move freely, which directly captures that idea. Flexibility depends on how far and how easily joints can move, influenced by the length and elasticity of muscles and connective tissues, as well as the joint’s own structures and neural control. It’s different from muscular endurance (how long muscles can sustain activity), power (how quickly you can generate maximal force), and cardiorespiratory fitness (the heart and lungs delivering oxygen to muscles). For example, being able to touch your toes shows flexibility in the hamstrings and lower back.
