I so love giving mho.....thanks for asking, MindiV!
1st. You look maaahhhhvelous, dahling.
2nd, I am seriously envious of your upper arms AND your hair. I could not get anything looking close to either of those attributes without some serious intervention.
3rd, and please, please, this is an oversimplification and a generalization from magazines which still tend for the most part to stress women being on the thin side. The rule of thumb that is simple to use as a little point of reference is that you should weight 100#s for the first 5 feet, and then 5#s for each additional inch. Again, I stress, just one generalization. At 5'8.5", that would make your "ideal" weight ~142.5#s. I know that for me, at 5'7.5", when I weighted 138#s, it was pretty ideal. When people told me I was too thin, I took it with a grain of salt because after an 80# loss, it was a pretty big change.
I can so relate to the "big boned" notion. I always thought I was too, and because I carried alot of wt. in my arms and shoulders and kinda straight up and down, people always said that too. After losing the wt. I realized I was medium, perhaps even small boned. Who knew? I don't think it matters much. What counts is health and fitness, and you obviously have that figured out.
Congratulations on great success and best wishes for your continued healthy journey.
