I am 5'7, 131 lbs and 34 years old. I do not want to go too small and have regrets!! I am very muscular (competing in figure competition in May). I am under 10% body fat but that will obviously go way up when I am done training. I went to my PS and we used the imager, we decided on the 650 one side and 700 cc on the other. Slight difference in starting size. See my pics to look at before and after. I don't think they look too big. How accurate is the image? I just don't want to be too huge! Any help is much appreciated!!!
