Yes, I have used it. It's really neat! It scans your body, and gives you a personalized workout plan that includes cardio, strength training, stretching, Has the instruction book with it. It's kind of hard to explain actually.
I wouldn't think so. It scans your body, asks your weight and height, gives your BMI, and gives you a personalized plan. You do have to exercise along with her, but I'm sure you could handle that :-)
