Picked up a Wii Fit a couple weeks ago. I've been walking for a half an hour four days a week since April and find walking on ice-covered sidewalks problematic.( The problem is splatting!) After reading numerous positive reviews on Amazon, I bit the bullet. It may not be up to snuff for the master athletes here but I am enjoying it tremendously. There is lots of feedback which I find very motivating and I am exhausted when I'm ready to quit a session. I am doing about an hour a day split into two sessions so much more activity that just walking. Has anyone else tried one?
