The Deluxe Aerobic Steps is a great high-calorie-burning workout. The deluxe aerobic step platform is adjustable up to 6 inches in height. You can adjust the height of the aerobic step to make it more or less challenging, depending on your level of comfort and/or experience. Of course, the higher the aerobic step platform, the harder you work - just like going up and down a steep set of stairs. You can eventually incorporate other exercises when using the aerobic step such as knee lifts, kicks, etc.
