A dance-based fitness class, led by an instructor, that first became wildly popular thanks to a Jane Fonda video in the early eighties. It has evolved passed its legwarmer-and-leotard clad origins and today there are as many styles as there are types of music.

Aerobic endurance makes the lungs work harder by increasing the body’s need for oxygen. As this oxygen is transported through your arteries, the heart’s muscles are exercised as it works to deliver the extra oxygen into the blood. This cardiovascular exercise improves the function of your heart, but in a fun way.
