I walk up and down the stairs in my house for about an hour.
**What a great idea to get some extra steps and a cardio workout! You can definitely get your heart rate up and give yourself a cardio workout by walking up stairs. You could walk the stairs continuously or do a few laps around your house, then go up the stairs a few times, which is similar to a High Intensity Interval training workout.
