Stepper Calories Burned. Using a mini stepper is comparable to walking, given that with the machine, you're essentially walking on the spot. The chief difference is that you can adjust the stepper to increase its resistance, which helps you burn calories at a faster rate than walking. A 175-pound person who uses a stepper for 90 minutes will burn 834 calories, which makes this type of workout slightly more beneficial than walking. References (4)
