I did Wii again last night..this time I did the Gold's Gym game. It's a boxing game that works on co-ordination and upper body strength. You have to complete each challenge to unlock the next one and it's also cardio too. When I finally quit I felt like it was a real workout. I have a Jillian Michaels work out too but I'm not sure when I will get around to fooling around with it.
