I think it's unlikely she weighs 100lb, not many women are that low. Though she is thin. But man that is small.
Him at 135? Maybe? I don't know how tall he is, but he is also very thin when I see photos. Could he be 5'8" and 135? 135 makes sense at that height as I've seen lots of high end runners at that kind of dimension. But I have no idea how tall he is.
