at my gym now, I would say a good 20 girls look as good if not better that do not compete. I don't understand what you are seeing, normal shoulders, normal arms for a very fit person who loves to train, a little bit of lines in the abs, 
12-13 inch arms, she probably can't bench a plate per side, certainly would never even suspect her of doing juice. I mean don't get me wrong she looks great but compare her shoulders to DLB's shoulders and you will see what difference juice does.
in all my time at the gym, i've probably seen 2-3 obviously female juicers... and apart from them (well, including them, they looked like absolute shit), i've never seen any girl in as good of shape as her. most female "regulars" don't look like anything special, and the random girl here or there who is in the same ballpark as Z., well in those cases i assume its mostly just genetics. what i'm saying is, 99% of females, including those who are in the gym 5 days a week, do not even look like they lift, in my experience. zuzana may not look like a fbber, fitness, or figure competitor, but she would stand waaaaay out in any gym i've been to.
