I know this is an old post, but I just thought I'd clarify some things about iShape.
First of all the program is $99 for a year, which is considerably less than previous posters thought.
As for the personalized aspect, the program has some short comings with regard to meals, but the strength and cardio plans are outstanding!
In addition, there is a great group of gals who support one another... a lot like this board, I can see :-) So far, I've lost 25 lbs and mostly by exercising and living a healthier life. Dieting is for the birds
The main draw though are it's logs. With them you can keep track of everything you eat and your cardio and strength training, too. Normally, I'd be on iShape right now, but they are upgrading the program today, so the site is down. At any rate, it's nice to be here.
