There are typically 12 steps in a flight of stairs. According to the Health Sciences Center of the University of New Mexico, climbing one flight of stairs three times a day burns about 15 calories for a person weighing between 150 and 160 pounds.
Regular stair climbing can help you lose weight, relieve stress, build stronger legs, boost your aerobic capacity, and reduce your risk of cardiovascular disease, among other health advantages. Walking burns half as many calories as stair climbing. Stair climbing is regarded as a green activity because it just uses body fat and requires no special equipment.
