What is the recommended time distance and rate should i walk daily?

Hard to generalize: Without knowing your health and fitness level, it's hard to say. There have been several studies that show that walking 10, 000 steps a day can be very beneficial (which is probably 4-5 miles for the whole day, including steps you routinely take around the house and work). But someone who is fairly sedentary might have to work up to this and someone in great shape might find this to be too easy.
