She looks like she's 4'9
Because that "perfect diet" is missing key ingredients like Anavar..She is short (sub 5'4") she's also a genetic freak with her muscle insertions and the capability to develop a bottom half that's more muscle than fat and still looked balanced (it's why she's short but weighs so much).
Your average woman could be in the gym for 6 years with a perfect diet and never look like that.
