Chicks dig the bulky look. Under 15% as long as you don't have a fat face.
10% is the best place to be with the women tho.
Chicks do not give a damn about veins in your abs, lats, your little christmas tree or your glute striations. If you don't compete and yet you want to regularly go under 8% you're a loser and most likely have mental issues.
10% is where it's at.
