Fact. If you stop exercising for a period of time, muscle size (also known as muscle atrophy) can decrease due to a reduction in the level of stimulus provided to the muscles. Regular exercise, especially resistance training, is necessary to maintain muscle mass. When that stimulus is removed, the body may begin to lose muscle size and strength over time.
