My office is located on the 17th floor of a glass building in Dallas. There are four elevators that can take me to my floor quickly, depending on the time of day. During times that I’m waiting for an elevator’s doors to open, I’ve often considered taking the stairs and walking up all 17 flights to my office. Then, of course, an open elevator appears.

Starting tomorrow, though, I’m walking up those stairs one step at a time. Sure, I can bound up them and reach my floor quicker, but according to recent research in PLoS, taking them one at a time burns more calories.

“The advice to those seeking to utilise stair climbing specifically as a method to control or reduce weight is to ascend stairways one step at a time; more calories are burned through this form of stair climbing,” the study’s authors wrote. “For example, climbing just a 15 m high stairway five times a day represents an energy expenditure of on average 302 kcal per week using the one step strategy and 266 kcal using the two step strategy.”

If you’re using a two-step strategy, you’ll have a much harder and quicker workout, expending more energy. However, if you take one step at a time, you’ll expend less energy but take longer to reach your destination, thus ensuring burning more calories.

What exercise routines are you starting this year?
