GamerFitnation's Zack writes about the Dance Dance Revolution & Just Dance series. "Dance Dance Revolution is the original rhythm music game. In the game, players follow the music and step in a specific direction on a gamepad on the floor. Just Dance is a more advanced version of DDR's core ideas. Both games require a fair bit of coordination to become skilled at playing, but they exercise different muscles. Both games can provide a good workout, but in different ways."
