EA sports active 1 vs 2?

I currently own EA Sports Active More Workouts for the Wii. I am interested in buying the EA sports active 2 because I love the other one so much. Is there anyone that has both and can tell me some key differences? The price is the only thing that is holding me back. I don't want to spend the money unless there are some noticeable differences. I know that the new one is now cordless and includes a heart rate monitor, but is that it? Are the workouts any different? Thank you!
