What is flexibility?

• A. the rate at which your body uses energy
• B. muscle density
• C. the ability to move your body parts
• D. cardiovascular endurance

Answer: (C)

Flexibility is the range of motion around your joints—the ability to move your body parts through their full, natural movement. It depends on how lengthened and elastic your muscles, tendons, and ligaments are, along with your joint structure. This concept is not about how quickly your body uses energy, which is metabolism; nor about how dense your muscles are; nor about cardiovascular endurance. You can improve flexibility with regular stretching and mobility work, which helps with daily tasks like bending, reaching, and tying shoes and can reduce the risk of injury.
