Muscles perform a variety of tasks throughout the day, and there are a total of more than 600 throughout the body. The main thing is that they help an individual lift things such as groceries, books, etc. Also, they are also a great source to burn calories because they can enhance a person's metabolism. The heart is a muscle which enables blood to move around the body. Individuals would not be able to walk or move around. Arms would have a hard time moving without muscles. Food could not be digested in the body because it helps move the food to the stomach.

Without muscles you would be a heap of useless flesh and bone lying on the floor unable to get up, breath, or live. So muscles are used to do anything and everything.
