What happens if I don't use my muscles?

    With muscle, you truly will lose it if you don't use it. Have you ever had your arm or leg in a cast? Do you remember how tight the cast was against your skin when the doctor put it on? Perhaps it even felt confining and uncomfortable. Within a week or so, the cast became looser, and you could see clear space between it and your skin. This was the result of disuse atrophy of the muscle. Essentially, this is what happens to your entire body if you don't actively use your muscles.
