Muscular physique on a female--hot or not?

Is it attractive for a girl to have a muscular body? To what degree?

Is the level of muscularity (if that's a word!) that is found attractive vary from body part to body part? (ex: a six pack vs really muscular and toned legs) Is it just the obvious definition, such as all the lines of a six pack, that are found repulsive (if at all)? Or is it the size in general?

Are guys intimidated by it?

Does it make her seem less feminine? Less girly? Is this a good/bad thing?
