Walking is good exercise, especially if you walk fast and get your heart rate up. Regular exercise can help you improve your fitness and energy levels, sleep better, and have a healthy body weight. Walking is ideal because you can do it anywhere. All you need is comfortable clothing and a good pair of shoes.
Health experts in the United States recommend that adults do an activity such as brisk walking at least 30 minutes a day, five days a week. Walk 10 minutes, three times a day, and you can still meet this guideline. Children need more exercise - an hour a day of moderate or more vigorous activity.
