2. Running Stairs [1000 calories/hour]
A simple flight of stairs is about to be your new favorite workout tool. Walking, running, or lunging up a flight of stairs provides a great big calorie burn. A 150-lb person running stairs for an hour can burn 1000 calories! Wow! That’s crazy!!! Of course, it’s probably just as crazy to run stairs for an hour! But you don’t have to. Get this: A person weighing 160 lbs. will burn 102 calories walking up and down stairs for 10 minutes. That’s a lot! Even better, you can do a great cross-training workout in 30 minutes or less and burn off more than a regular running session. Look for an outdoor staircase near you that has more than one flight. If the weather is bad, use that simple flight of stairs in your home instead.
