Well perhaps it doesn't.... Hmmm guess I never really thought the mechanics of it through.
Anyways, I got a buddy of mine to do an 11 point skin fold test and according to that test, I'm 10.73% bf. I'm very happy with this result.
Oh ya, thought I should also mention that tanning and then running is a bad idea. Tanning sucks the energy right out of you. Also, don't use tanning lotion on your first time...I'm burnt and patchy...

Oh well, now I know.
