Aerobics refers to physical exercise that increases your heart rate and makes you breathe harder. You've probably seen people running or dancing in groups while doing aerobics.
When we talk about aerobics, most people think of a group fitness class where everyone is moving together - it might be aerobics with weights, step aerobics, or Zumba, which are all popular aerobic exercises. These classes usually involve jumping jacks, running in place, and other energetic movements that get your heart pumping. You can also do solo aerobics at home, following along with a video or app, or join a recreational sports team for some friendly competition.
A form of exercise, designed to enhance one's cardiovascular fitness, normally performed to music.
