No aerobic workout is complete without the presence of an aerobic step. From traditional cardio classes and step aerobics, to kickboxing and even yoga, a step is definitely an aerobic must-have. Most routines, whether at home or in the gym, make use of this important piece of equipment at least during some portions of a routine. Intended to help exercise and develop the lower body, especially the quads and the calves, an aerobic step is an absolutely necessary part of any aerobic routine. Aerobic steps provide an additional challenge during an exercise routine, and they serve as an important element to specific aspects of specific routines.

This particular model, the DF-SD039, is constructed of a heavy-duty, durable plastic designed to take the impact of, and make it through even the most difficult routines. This aerobic step includes adjustable legs intended to increase the height of the platform, allowing for a more individualized workout. An increase of up to six inches of height can be achieved with the step's adjustable legs. Individuals who are more comfortable with a routine can adjust to a greater height, while beginners can keep the step closer to the ground.

The step's specially designed, shock-absorbing surface provides increased comfort and helps prevent foot pain and potential injury. The same material is also designed to provide excellent traction for those sweaty workouts. The floors at home or in some gyms can be very slippery, and the additional traction on the platform's feet helps increase safety by preventing slippage.
