I think the rules explicitly said that they were not allowed to work out during the 4 hours in the room. But given their strong losses for the week, I am thinking that was just for the camera and they were allowed to do exercises.
I loved the card deck workout, and I have to say that it really does show the power of the show IMO. I've been on my plan for almost 2 weeks and have lost almost 10 lbs (I don't update my ticker until Sunday). Those numbers are pretty high, not BL numbers, but good. However, the change in my fitness level is marginal at this point. Even conceding that BL "weeks" are a flexible concept, it's still incredibly impressive to me what those blue team players were able to do after just 3 "weeks" at the ranch. I don't know that I could have lasted through the first 4 cards!!
Restart 1/6/13 - GOAL (for now) back to prior low
