I weigh 106 and have a bit to pinch when I am standing, but I still have a 26 inch waist. My body fat is around 18%, and that loose skin is bothering me. I have never had it in that area before. When cycling season winds down, I am going to work with a trainer. I still do core work at home, but I need a push here. I've always had jiggles in my rear, it's just half as small as it used to be! Probably only 100 squats a day would cure that. I am aware, but I know what I have to do.
As far as the kids, I tried the same thing as V when I was teaching. I also had the girls who didn't eat; it was either/or in many cases.
