According to Shape Magazine, a person can burn up to 400 calories in 30 minutes on a stair stepper. On average, a person who weighs approximately 150 pounds burns about 100 calories every 15 minutes, using regular settings. The amount of calories a person burns varies based on the intensity level.
The number of calories that one burns on a stair stepper varies based on individual weight, metabolism, and the length of time spent on the machine. It is possible to increase the number of calories burned, by increasing the difficulty on the machine. Many stair steppers calculate exactly how many calories are burned during the exercise routine.
