Do a whole body mini workout on the stairs. Do one set (15-20 reps) of:
-Stair-push ups (like wall push-ups, but uses more of your body weight)
-Step-ups (take two stairs if you can)
-Single-leg calf raises
-Then sprint one flight up and back down.
Repeat as many times as you can in 10 minutes .
I have stairs at home, and can manage to fit in this mini work out three times a day.
