Quizplus · Accepted Answer

This is true. As people age, there is a natural loss of muscle mass, known as sarcopenia. However, the rate at which different muscle groups shrink can vary. Back and leg muscles tend to shrink faster than arm muscles, which is why it's important to engage in regular physical activity that targets all major muscle groups, especially the back and legs.
