The Aerobics Radio is given to the player from the Aerobics Festival in Animal Crossing. Every time the player goes to the Aerobics Festival, Tortimer may give him or her a card and a stamp. If the player goes fourteen times, the Aerobics Radio may be received.
The Aerobics Radio allows the player to perform Aerobics at his or her house. Only one radio can be on in a house, so if the player turns a second Aerobics Radio on, the other radio will turn off.
