Definitely a tough call. Of course Renee Toney STILL is the lone lady to crash the amazing 20 in bicep barrier and when one looks at other huge ladies like Nataliya Kuznetsova, Colette Guimond, or Virginia Sanchez- they're already huge! One wonders where they would fit those extra inches they're lacking to match Renee's achievement.
I'm going to go with Colette though. IF she was taller she would have more room to grow and her biceps are absolutely bullet proof!
