For my personal opinion, this is really good for the health, however, if you have the heart problem, you have to be extremely careful by dancing only 5-10 minutes at a time and dance softly because if you are unexpected tired , it may aggravate the heart health, and make you cannot breath properly at that moment which can cause the serious heart condition at that moment. If your health is not good, you can do it at home by purchasing the aerobic dance DVD online. If you have fun when you dance, it will encourage you to do this kind of exercise every day which will really make your health stronger. Buy various kinds of fun aerobic dance DVD, so you will not be bored to dance the same steps everyday.
