I don't have that one. Just the regular wii sports.
Boxing gives me the biggest workout in that.
For the most part, the ones with the balance board give me the most mid-lower body work out and the boxing (so far) is the best aerobic. I'd be interested though in the ones you guys think are the best.
I have made a note to try the hula hoop and ski jump

We just got Wii Fit Plus. It has some fun new additions. The boxing is great, the karate not so much of a work out, but it gives me the giggles 
are the hula hoop and ski jump ones part of the Wii fit? do you need the balance board?
Yes and yes!
