Often overlooked in favour of more intense workouts, walking is actually one of the most important and beneficial forms of exercise. Physical activity doesn’t have to be complicated and doesn’t have to be vigorous or done for a long period of time to improve your health. One of the best things about walking, is that its free! It doesn’t require any special equipment or training and is a great form of activity for those that haven’t exercised for a long time, or who are overweight or elderly.
