Exclusive: Climb Some Stairs and Stay Fit with MFF's Harold Gibbons!

If climbing stairs for cardio is new for you, start by simply walking up and down the stairs. Your heart rate will climb as you do, and the descent will be a chance for your heart rate to settle as your body recovers. For a more intense kick in the cardio butt, you can take the stairs two at a time, which makes the muscles of your legs and hips work harder. To up the ante even more, running up the stairs - probably two at a time - will require the most strength and elevate your heart rate the quickest.
