maecrispy- Sounds like you're *really* in good shape

How do you get your bodyfat measurements?
And if your bf% didn't go up, but your weight did, then yeah, you *did* gain muscle. With all the climbing, I can see why you wouldn't want any extra weight (of any kind).
Oh, and I dunno if you're the shortest guy here. I think at least one Autopian is around 5' 4".
