If you have a set of stairs and a pair of dumbbells, you can get in a solid heart-pumping, butt-kicking, arm-toning workout — and in just 13 minutes! You can spare that in your day, right?
Directions: Grab a pair of 3- to 10-pound dumbbells, or two sets so you can use lighter or heavier weights depending on the move, and let's get started. Here's the workout with explanations of each exercise below.
Note that if any of the moves are too difficult, focus on one part of the move — either the legs or the arms. You can also just skip the dumbbells altogether and hold imaginary weights.
