Yeah, yeah, it’s technically running. But this kind of running offers more bang for your buck. Run up the steps at a stadium one step at a time, and you’ll hone footwork, improving your athleticism. Bound up two stairs at a time, and you get to drive your knees high with every stride, something that’ll make you faster when you hit flat ground for a more “traditional” run.

You’ll build plenty of endurance running stairs, too, and a pair of rock-solid calves if you do it right. Work hard to stay on your toes as you run. A bonus: It’s a perfect indoor hotel workout if you can find a stairwell.
