You’ve been using a significant amount of energy ever since that first tottering step you took as a child. Walking is an easy, painless and powerful form of exercise. Studies show that you burn about 100 calories for every mile you walk. This may not sound like much, but it quickly adds up.
The ideal walking program consists of a minimum of a 20-minute walk at least three times a week. To enjoy maximum benefits, don’t just drag your feet along the sidewalk but get your whole body involved. Bend your elbows, flex your hips and torso, relax your chest and shoulders and take brisk steps at a comfortable but challenging stride.
