Muscles are soft tissues in our bodies that help us move. They work by contracting and relaxing, allowing us to perform everyday activities like walking, running, and lifting objects. There are three main types of muscles: skeletal muscles, which are attached to bones; smooth muscles, found in organs like the stomach; and cardiac muscle, which makes up the heart. When we exercise, our skeletal muscles get stronger and more toned. This is important for overall health and fitness. Eating a balanced diet and staying active can help keep our muscles in good shape, making it easier to enjoy life and stay energetic.
