Walking is simple, free and one of the easiest ways to get more active, lose weight and become healthier. Sometimes overlooked as a form of exercise, walking briskly can help you build stamina, burn excess calories and make your heart healthier. You do not have to walk for hours. A brisk 10-minute daily walk has lots of health benefits and counts towards your 150 minutes of weekly exercise, as recommended in the physical activity guidelines for adults aged 19 to 64.
