Jenny Saville said that the best way for her to paint her subjects was to understand all she could about that chosen subject. For example if she was painting a women with stretch marks she would research medical books to understand why they accrue so she could create a accurate conclusion.
Taking a page from Savilles book I have done a little research of my own about my chosen subject on female body builders. Majority of people that I have spoken to when discussing Female bodybuilders has resulted in a debate about steroid use. Because it is not the natural order for a female to be a big as a man, I looked for stories about women that had taken steroids and came across this article on the daily mail online website.
