Just Dance is definitely good for getting a sweat on. I also use EA Active Sports 2. This game comes with a heart rate monitor, leg sensor and a resistance band. You can choose to do a 3 week introduction programme or do a 9 week programme. You are asked to work out 4 times a week with the workouts lasting around 30mins. The workouts include warm up, cardio, resistance training and a cool down. You can also create your own workouts. I do the 9 week programme and after I have done the required workout I do half an hour of step with my wii balance board. This is the best fitness game I have had for the wii. Wii fit wasn't intense enough for me and I never got my heart rate up.
