Hell, I'm 5'9 my husband has told me he wouldn't want to see me go below 170. Bunny is the same height as me, she competed in figure, and won, I think she was in the mid to low 150s (I think.) but I think you get my point.
Like I said, those charts are such complete bullshit for weight lifters, you have to go by bodyfat, which is why you may want to go to your personal physician and get the testing and forms filled out there, which you can request.
