Welcome to the muscles. Muscles are responsible for your body's every single movement. Muscles keep your gut from sagging and your lungs pounding. Muscles are more than movers. Muscles make the heat that keep you warm. If you leap, bend, or reach, this is a result of a muscle action. A muscle makes itself smaller when it contracts and larger when it relaxes.

I am investigating the different muscle groups that boys, girls and adults use each day.​ The muscles we use each day most likely will be the same, but sometimes it will be different. I have to test three people that are different ages. I have only tested one person, which is an adult.
