Bnsafe, I will certainly will defer to Robby or Les on this (they have a lot more knowledge and training than I do), but it seems to me that 185lbs is a pretty reasonable weight given your height. The numbers you provided indicate a body mass index of 23 which is within the healthy weight range (I am not a huge fan of BMI but it does serve as a useful tool in that it can give a range of healthy weights based on height). Take 10 people of the same height and at healthy weights, and you are going to see a fair amount of variety in how their frames are built and how they carry their body mass. I am 5'3, and the healthy weight range for a woman my height is listed by the NIH as 111-147lbs....that is a pretty vast range, and I can tell you that as a girl with curves who builds muscle rapidly, I will never weigh 111 pounds unless I am seriously ill, but that 147 is pushing overweight on my body frame. Given my build and frame I am probably at my peak performance someplace closer to the midrange, around 130-135lbs. No amount of calorie restriction or working out is going to give me the frame of a 90 lb ballerina, and I doubt I would have any endurance at that low weight either
