Step aerobics is a form of aerobic activity which is
performed on a platform that usually ranges from 4" to 10"
in height. Step training was developed to provide a low-impact
activity that is both challenging and interesting. People who
may not like certain aspects of aerobic dance find that step is
a very good alternative. Each participant works within his or her
own space. There is no traveling across a room. When done properly,
step training is an efficient means of improving aerobic fitness.
