Pregnancy Sculpt

Has any one out there tried Andrea Orbecks Pregnancy sculpt Dvd? I just did my first round and let me just say wow lol my buns can feel it. Was just wondering if any ladies out there had been doing it to share stories

and also I was wondering what everyone found easiest with a body media device or a fit bit device to put there cals at a low number and eat back all their activity calories or to set it at a higher number and just stick to that number and not worry about your net calories? I have started putting the weight on a little fast at 21 weeks as I started out 41 lbs over weight to begin with and would like to just slow the weight down a little my dr said aim for about a .5-1lb a week from here on out and I feel like i'm putting that on a day!
