Regarding Amy (I am a former bodybuilder)
I've spent some time looking at her very carefully, and it is my own personal opinion Amy may have a past history of steroid use. As someone who has spent time around quite a number of female bodybuilders who turned to steroids for help, Amy shows some of what I believe are classic signs of steroid use.
If you have any interest in making a comparison, Google Candice Armstrong, a female bodybuilder who admits to having used steroids. I think that if you take a look at Candice, you'll notice some similarities to Amy, particularly in her masculine facial structure.
Not passing any judgement on Amy if that's a choice she made in her competitive past, but it hasn't gone unnoticed that Amy does look more than just a little manish.
