Our bodies are amazing, made up of moving parts that when put together make miracles happen. And more than 650 of these body parts are muscles. It’s hard to believe there are so many inside one body, but some are super small while others are massive. Keeping our muscles toned and healthy is important for our bodies to be at their best. Exercising and eating well help our muscles grow and repair. It’s not all about flexing, but more about function.
