Keep up the great work. You may not believe it right now, but, you are making great progress. I believe you are on the path to realizing your goals. The 15 day fit test shows that, give the program the same intensity you have been for the remainder of the workouts. At that time you can reasses the progress. Most people report experiencing a noticable difference in week 3 and beyond. Hopefully, you should be close to a breakthrough. One last thought, try to avoid the scale for a week or two. That wonderful piece of technology only tells part of the overall story

I hope this helps. Remember, you are not the first to be feeling this way so early, you've got a lot of company. I just finished the Body Beast and actually increased my waist size.....gonna be working on THAT!
