I will be starting week 6 tomorrow! I have lost 12 lbs since August 1st, not too bad considering my doctor said I was "morbidly obese". I keep up for that most part and slow down when I need to. when I can't do one of their moves, I will just jog in place to keep my heart rate up. It's been tough, but I really need to get this weight off, and so far this has been working for me
