I was in 4 grade and the teacher was talking about how big and strong the Indian women had to be to carry those big jugs of water from the river up to the camp.  He said they must have had massiuve msucles!!  It started there!!

if we talk only about the "growth thing" and not the muscular part, i would say that it started.. in my dreams!

the first time i "saw" a woman become quickly muscular was in fact in one of my dream, when i was a kid... i didn't know very well what to think about it, i ve just discovered the world of muscular women...

then, i saw a fews pics that represented what i ve dreamed, like some she hulk sequence, or in some cartoons, like tiny toons...
