Those of you who have completed either one (or both), would you feel it would've helped or hurt you during SFAS?
A little background to help answer the question in the direction I'm most looking for:
Today is the final Fit Test for Insanity for me, and I was planning on picking up P90X and repeating Insanity for the next two months. I have heard that large amounts of muscle can slow you down in SFAS which will hurt you in the long run.
A more direct question may be "Would the amount of muscle this routine will build be a positive or a negative when preparing for SFAS?"
Thank you.
