Stairmasters are phenomenal and challenging pieces of fitness equipment. Now if you are referring to a stepmill which is a revolving set of stairs then this machine is even more of a challenge. Any form of movement will help your burn calories as your body is active, your body temperature is rising, and your body is working to cool itself which results in calories burned.
To be more specific, a stairmaster will assist you in burn calories by preventing yourself from letting either foot hit the ground. You must make your body work to keep yourself balanced and keep yourself upright. Again, this machine will be very challenging. A stepmill is a very similar machine but instead of staying in one place, you are constantly climbing. This challenge requires balance and requires that you do not fall off the steps, sounds easy, right? A stepmill can surely present a challenge and burn plenty of calories! When using either machine be sure to try and not use the handle for support, try and use your strength and balance and you will truly benefit even more!
