What is the best exercise game for Nintendo Wii?

I mean in terms of physical overall body movement. I know the Wii console alone is designed to exercise the body. I think it just mostly works the upper body and not enough of the lower body.

I was just wondering which game currently out there is best for exercising the overall upper and lower body?

I know Wii is coming out with DDR pretty soon. DDR is still cool. I'm just looking for something new. Any sites out there that focus on the Wii console and tells us which games works out which body part? Thanks.
