When it comes to working out, there's one thing you can do for yourself every day. Sore muscles may keep you inside on your rest-day, but there's one thing you should get up and do. And that's walk.
Walking may not be as glamorous as squatting 200 pounds or sweating it out on the stair-master, but for just 30 minutes a day, you can greatly improve your health by walking instead of watching T.V. or lounging on the couch.
Walking is a low-impact exercise...so you won't damage your knees from doing it. According to the American Heart Association, walking offers an assortment of health benefits such as decreased blood pressure, reduced risk of heart disease, as well as improvement of mood and overall mental health.
