Read the rough-draft paragraph. Exercising daily is one of the best ways to help the body fight fatigue, illness, stress, and weight gain. Whether taking a bike ride, enjoying a walk, or going for a swim, the type of activity is not as important as exercising consistently. Often, people begin the new year with the resolution of exercising, but within a few months that commitment is quickly forgotten. The key is to choose something that is accessible, enjoyable, and affordable. Exercising just thirty minutes a day not only strengthens the heart and lungs, but it also helps to boost one’s energy. Another way to feel more energized is to eat a balanced diet. Since no single food item can supply the body with everything it needs, it is important to eat a variety of foods. So to maintain a long, happy life, get out there and get moving, and enjoy a wide range of healthy meals.
