You burn about 0.17 calories for every step you climb, so you burn roughly a calorie and a half for every 10 upward steps. 4. You also burn calories going down. Every stair descended burns about 0.05 calories, so you burn 1 calorie for every 20 steps down.
Example. 10 steps going up = 1.7 calories meaning 20 steps (1st floor) = 3.4 calories and if you office is on the 5th floor it equates to 17 calories. And coming down 100 steps (5th floor) = 5 calories. So in total you burn about 22 calories going up to the 5th floor and back down. If you do this 5 times a day you will burn around 110 calories – more than a bag of salt and vinegar walkers crisps!!
