I am using the wii fit and a Julian Michaels work out game. It is working for me so far. The wii is cool because the daily body tests show your progress on weight and BMI, I enjoy seeing my own personal progress. I get to personalize what I do, and if I'm sore and can't do something, then I decide on what I am doing.
I have wasted so much money on gym memberships that never happened, so this works good for me.
