I think you and I have alot in common!
We both started the same day and had similar body compositions. In my first week I lost 9 and I feel very similar to you! I agree with your assesments of the work outs and increased energy levels. I don't know about you, but I already "feel" like I am in better shape, which encourages me to stay eating well and sticking to the TT workouts.
I wish you the best of luck and hope you continue to be this excited through the program!
