Exercises are physical activities designed to improve strength, flexibility, endurance, and overall health. They can include a variety of movements, such as running, swimming, cycling, and weightlifting. Regular exercise helps maintain a healthy body weight, boosts the immune system, and reduces the risk of chronic diseases like heart disease and diabetes. There are different types of exercises, including aerobic, anaerobic, and flexibility exercises. Aerobic exercises like jogging and dancing increase heart rate and improve cardiovascular health. Anaerobic exercises, such as weight training, focus on building muscle strength. Flexibility exercises, like yoga and stretching, enhance the range of motion in joints and muscles.
