4. Strengthen your heart. Even a modest pace is enough to keep your heart in good shape. Walking has been shown to lower levels of bad cholesterol while raising good cholesterol. It's also good for your blood pressure. And it reduces your risk of heart attacks and stroke. Thirty minutes a day is all it takes.
5. Control weight. A walk won't undo the ravages of a triple bacon cheeseburger, but it does burn a few calories. More importantly, walking helps to keep your metabolism in shape. Excess calories are dealt with more effectively.
6. Walking is cheap and easy. Aside from a pair of shoes, you don't need anything to go for a walk. There's no complex skill to learn or expensive equipment to purchase. Walking is an option for nearly anyone, regardless of age or current fitness level. It's easy on your joints and carries a minimal risk of injury.
