Whatever your age, gender, or health status, you can benefit from exercise. As large, long-term studies have shown, increased activity, even in middle age, can reduce the danger of dying before one’s expected time. Even light exercise (any activity that increases oxygen consumption less than three times the level burned by the body at rest) can improve physical and emotional well-being. The more active you are, the more benefits you gain.
Here are some of the health benefits of work out:
Improve cardiovascular fitness.Regular activity strengthens the heart so it pumps blood more efficiently. The body easily takes in all the oxygen needed for these activities, so your heart and lungs don’t really get a workout. This is achieved through aerobic exercises such as walking and swimming.
Tone muscles.With exercise, muscles become firmer, function more smoothly, and are capable of withstanding much more strain.
Reduce stress.Working out releases tensions and enhances your ability to deal with daily challenges. Even when your schedule gets jammed, carve out 20 or 30 minutes several times a week to walk, swim, bicycle, jogs, or work out at the gym
Improves mood.In various studies around the world, physical exertion ranks as one of the best ways to change a bad mood. Exercise may be the single most effective strategy for changing a bad mood. It also works wonders for reducing anxiety and depression.
Burn calories.Exercise speeds up metabolism, so the body uses more calories during and after a workout.
Increases flexibility.Exercise stretches and lengthens muscles and increases flexibility in the joints. Both muscles and connective tissues, such as tendons and ligaments, shorten and become tighter if not used at all or not used through their full range of motion.
Enhance strength and stamina.Muscle workouts improve the circulation of blood in the tissues and increase the body’s ability to do sustained work. It’s not enough to be able to hoist a shovelful of snow; you’ve got to be able to keep shoveling until the entire driveway is clear.
Keep bones strong.Regular physical activity (especially weight-bearing activity) thickens the bones, possibly preventing the slow loss of calcium that normally occurs with age.
Lower the risk of disease.Exercise helps prevent many serious health problems, including high blood pressure, strokes, heart attacks, and certain cancers.
Live longer.Physical activity slows the aging process, so you remain healthier and more active for a longer time. And if you work out often and vigorously enough, you can actually put more life in your years—and possibly more years in your life.
