If you're trying to lose weight and want a new way to do it, stair-climbing as a regular exercise - or just adding a few flights a day - might be for you.
It's accessible, and research shows it's more effective than walking on level ground.
"Overall, it is a fact that stair-climbing gets you fit faster and consumes more calories," said Lauri van Houten, vice president of the International Skyrunning Federation, which oversees a wide range of disciplines that involve vertical climbing.
This includes disciplines like mountain running above 2,000 meters (about 6,500 feet) or events like the Stairclimbing World Championships.
These competitions are for the very fit, but we're talking here about adding a few minutes of stair-climbing as a daily routine and raising awareness about its effectiveness for all ages.
