chick, let me start by saying I sincerely respect your knowledge and achivements and insight into Bodybuilding-
However, for the sake of clarity, it should be mentioned that the 2-3% bf you speak of in competition shape is not physically possible. Let me explain... before I sound like some armchair lifter who's never competed: Calipers and some bodyfat testing procedures WILL in fact show 2-3% BF for comp. pro bodybuilders, but the actual bodyfat is higher than that.. by a few percentages. Muscle itself is not 100% lean, but also contains some fat. I do not know the exact numbers, but I do believe it may be around 1 maybe closer to 2% of a muscle that's fat. This is fat inside the muscle, and is not dieted away for competition, as it's a natural part of muscle. Given that the human body itself is a somewhat "fat" organism/animal, NO human will reach such a low bodyfat percentage without dying or being very, very close to death, and such a person would not hold muscle. In fact, the most accurate testings to test BF% show that pro BBers are 5-6%+.
just wanted to put that out there. Thanks for the thread & info and for answering questions.
