I started doing this workout couple of times a week when I was running out of time at the Hurt Locker. If I am press for time at the gym and can only get in some weights then I would do this HIIT cardio at home. Given you have stairs at home try this and let me know what you think. I usually am out of breath after the first set.
Skater runs up the stairs, when you get to top do 10 jumping jacks. Walk back down.
Repeat 3-4 times. Aim for 3 sets.
