Flexibility! :)

Explanation:

Agility: The ability to rapidly and accurately change the direction of the body. It is important in sports such as tennis which requires players to change direction quickly to hit the ball.

Flexibility: The muscles’ ability to move a joint through a full range of motion, and staying flexible is important to health and performance. As the body ages, the muscles, tendons, and ligaments stiffen, lose elasticity, and become less flexible.

Power: The ability to move the body parts swiftly while applying the maximum force of the muscles.

Body Composition: The combination of fat mass and fat-free mass, including bones, muscles, organs, and water.
