Step Up to the Challenge. Strap on a pedometer and find out how many steps you take each day. Gradually add just 250 steps per day averaged out over the week. That will give you a good start on a healthy routine of physical activity. Most sedentary adults take only 2,500 to 3,500 steps a day. Aim to add between 4,000 to 6,000 to whatever you are doing now, for a total of 10,000 or more each day. The more steps you take, the better.
