Muscles are important for moving you around, without them you will be like a couch potato. The toner or stronger your muscles are, the better you can move around without tiring out. Having stronger muscles can make your life easier because you can lift heavier objects and move around better. When strengthening muscles, be careful not to build too much muscle mass. Having too much muscle mass can drain you of energy because bigger muscle burns more calories. Exercising is one of the best ways to tone or strengthen muscles, but without food, exercising is worthless.
