How does muscle strength impact mobility?

Muscle strength plays a crucial role in determining a person's mobility. Strong muscles contribute significantly to overall stability and movement efficiency. When muscles are weak, they can hinder a person's ability to perform daily activities, such as walking, climbing stairs, or maintaining balance. Weak muscles may not provide the necessary support for joints, leading to potential instability and an increased risk of falling. Mobility is not only about performing athletic activities; it encompasses all forms of movement, including routine actions that require strength and stability. Therefore, weak muscles can severely limit an individual's mobility in various situations, making option C the most accurate choice.
