Does poor muscle health lead to muscular dystrophy?

How you personally take care of your muscles is not related to whether or not you will develop muscular dystrophy. Muscular dystrophy is caused by defective genes, which affect the muscle fibers and make them weak. Muscular dystrophy usually affects the voluntary muscles but may sometimes affect your internal organs and the heart. If you have muscular dystrophy, it is important to maintain as much range-of-motion in your limbs as possible. Exercising your muscles and keeping your joints flexible will help to delay the progress of the disease.
