I started a post about this a while back but got no replies. I have it and love it. I also have the wii fit but like most others only ever did the step and boxing and found I didnt really turn it on.
I am now half way through a 30 day challenge on the active and I find this keeps me honest. It also gives you rest days which is good. I already feel heaps better doing it and the squats are a killer and thats on easy. Cheeky monkey I dont consider myself unfit but geez easy level is where I am staying for now. If I dont feel that I have done enough on this level I have made myself a custom boxing workout and I do that aswell.
