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)
The act of jogging requires more muscle engagement, which leads to more calories burned. Mini trampolines, which are common at many gyms, are ideal for jogging. A 125-pound person will burn 200 calories in an hour of jogging on a mini trampoline and a 185-pound person will burn 294 calories during the same workout.
