Haven't started the new workout yet. I just finished the ultimate reset and you're not supposed to workout during it. I was already skinny and I lost another 11# (and I was cheating that last week so I didn't lose any more!).
I am just doing a P90X/Insanity hybrid for the next week or two to get back into it, and then I start the body beast. I'm going out of town this weekend so I wanted to wait til that was over. I did do some nutrition mapping today...gonna be interesting to say the least! I have been eating <1000 calories per day and been vegan for 3 weeks...now I'm jumping up to 2600!
