Which term best matches the description: the ability to store energy?

• A. Stamina
• B. Power
• C. Balance
• D. Flexibility

Answer: (A)

Stamina is the term that best matches the idea of sustaining work over time by leveraging the body's energy stores. Your body keeps energy ready for use by storing glycogen in muscles and the liver, plus fat for longer efforts, and stamina describes how well you can convert those stores into repeated effort and resist fatigue. In practice, stamina reflects endurance and the capacity to continue performing work before fatigue limits you.

Power, on the other hand, describes how quickly you generate force in a short burst; balance and flexibility pertain to movement control and range of motion, not energy storage.
