Muscles are important for a variety of reasons. They allow us to move our bodies and enable our internal organs to function. Muscles are made up of different bands that interact to allow the muscle to move powerfully and smoothly. Maintaining muscle strength is important for balance, flexibility and bone health. To keep muscles healthy, it is important to exercise regularly and eat a nutritious, balanced diet.

- Muscles are important for movement and internal organ function
- Exercise is important for muscle strength

- Skeletal muscles are striated, meaning they consist of thousands of equally-sized muscle units

Muscles are important for movement and internal organ function
To maintain healthy muscles, it is important to get regular exercise and eat a nutritious, balanced diet. The Academy of Nutrition and Dietetics recommends doing muscle-strengthening exercises for the major muscle groups at least twice a week. People can strengthen muscles by lifting weights, using a resistance band, or doing everyday chores, such as gardening or carrying heavy groceries.
Protein, carbohydrates, and fat are necessary for building muscles. The Academy suggests that 10-35% of total calories should be protein, with good quality, low-fat carbohydrates, such as wholemeal bread, plus low-fat milk or yogurt. Maintaining strength in the muscles is important for various factors, including balance, flexibility, and bone health.

Exercise is important for muscle strength
Muscles are important for a number of reasons. They allow us to move our bodies and enable our internal organs to function. Smooth muscles are responsible for movements in the stomach, intestines, blood vessels and hollow organs.

Exercise is also important for maintaining muscle strength. Muscles can contract rapidly and with a lot of force, and this type of muscle is responsible for most of the body's muscle strength and its increase in mass after periods of weight training.

Muscle-strengthening exercises are recommended for major muscle groups
Muscles are important because they allow us to move our bodies and enable our internal organs to function. Medical professionals recommend exercising to develop muscle strength, which is important for balance, flexibility, and bone health.
Muscle-strengthening exercises are recommended for the major muscle groups, which include the legs, hips, chest, abdomen, back, shoulders, and arms. These exercises can be done at least twice a week and can include lifting weights, using resistance bands, or even everyday chores like gardening or carrying heavy groceries.
The different bands within each muscle interact, allowing the muscle to move powerfully and smoothly. Smooth muscles are responsible for movements in the stomach, intestines, blood vessels, and hollow organs. Skeletal muscles are striated, meaning they consist of thousands of equally sized muscle units with transverse bands. When these bands relax or contract, the whole muscle extends or relaxes.

The Academy of Nutrition and Dietetics suggests that 10-35% of total calories should come from protein and recommends good quality, low-fat carbohydrates such as wholemeal bread, as well as low-fat milk or yogurt.

Skeletal muscles are striated, meaning they consist of thousands of equally-sized sarcomeres, or muscle units. A striated muscle appears striped under a microscope because of the transverse bands within each muscle unit. When the bands in the sarcomeres relax or contract, the whole muscle extends or relaxes. This allows the muscle to move powerfully and smoothly.
