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)
According to my favorite calorie counting app, My Fitness Pal, you burn an average of 211 calories per hour just carrying your baby around. Add in pushing a stroller while babywearing for 6 minutes and you burn 381 calories. If you're pushing a double stroller, I am sure it's over 400 calories burned. Better yet, if you are out one-on-one with baby, ditch the stroller! Strap on an ergobaby and head out the door.
