Okay, didn't read all the replies as I'm short on time but here is my review...
I LOVE my wii fit!!! I have been using it for 72 days now (it tells ya this every day). I would HIGHLY recommend the Wii Fit Plus, I'll get to why. SO in 72 days I've dropped 11 pounds and 3 inches on my waist.
I'm thrilled. I do the yoga and strength training. The original is annoying having to choose your thing each time... the plus has a training routine you can set up. You go in and choose the ones you want to do and it goes through each one no stopping. It's great. I would suggest you do them individually first though so you get used to how to do them and all. You can do a body test daily, so it keeps track of what you are losing constantly. At first I did not like this, you see when you go up too
but it's actually a great thing. I find the best use for this is going to be when I lose all the weight I want, I'll be checking it daily so I'll immediately see if it's starting to go up and that I need to watch what I'm doing. Now I am also following a lot of the weight watchers point system... my sister is in it and has helped me with what I'm eating, what the points are etc, and I'm sure this is helping me. All together these two are perfect for me. However I'm sure you don't have to do the weight watchers, just know that you will need to keep an eye on what you are eating too.
I truly can not completely communicate how wonderful the Wii fit has been for me, how much I do love it ( and I HATE exercising, HATE sweating). Like anything else it is something you have to actually do regularly for it to work but for it to work for me who hates exercise and for me to love it so much it's a wonderful thing. I'm able to make myself get up an hour early every morning to do it, plus I usually do more later in the day it's so much fun!!!
Good Luck
Okay, kids settled and I read more posts, it most certainly DOES give you a work out. It takes several days or a couple weeks to realize it, but I feel my stomach is harder now, I can hold the yoga poses easier, longer, more steady... I can do more reps of the strength training, it does give you a work out and does work.
