エアロビクス エアロビック・エクササイズ
A style of exercise that combines cardio exercise with stretching and strength training.

While it is still practiced today, it was notably very popular in the 80s, where it was usually practiced in groups with an instructor. It was also the subject of many exercise videos at that time, which are notorious for the tight-fitting and colorful [[leotard]]s and [[bodysuit]]s that the instructors and participants typically wore.
