I did some yoga on my wife's Wii Fit last night and it's not easy...and works well. It doesn't look like you're doing anything strenuous but it requires a lot of balance and very strong legs to hold some of those positions...it was tough and I lifts weights almost daily.

My back was stiff from carrying my fat baby daughter around for a few hours so I wanted to stretch it out. It worked for my back, then my legs were sore! It tightened up my abs nicely too.
