Been using the Wii for about 4 months, two to four times a week. I like that it forces me to weigh myself and admit to myself that I am overweight, and it tracks my exercise and daily weight changes.

As for the actual exercises, I see it more as warmup (yoga), toning (strength-training), calorie burning (aerobics), and cooldown (balance) and run through them in that order for a total of about an hour. As I bought a fluid trainer last month, I have been doing alternating Wii/trainer during the week, and ride on Saturday/Sunday, with Fridays off. Yea, been loosing weight slowly as I am not 'dieting', just cutting out the garbage (like the icecream I used to eat after dinner). Since June when I started riding again, I lost about 25 lbs. Have another 25 to go.

New diet/exercise titles are being released now; I saw one at Toys-R-Us as I was holiday shopping a few weeks ago.
