If muscles atrophy, they...

Explanation:
When muscles atrophy, they waste away. That means they shrink in size and mass, often from disuse, aging, or disease. Fewer signals for building muscle protein and/or more breakdown cause the muscle fibers to become smaller, leading to weaker, smaller muscles. This is different from stiffness (which would make muscles feel firm or rigid), fatigue (a temporary state from activity), or gaining strength (which would mean the opposite of atrophy). With proper use, like resistance training and good nutrition, muscle size can increase again.
