Throw the scales away and get a fabric tape measure and a book. With the work, workouts you have been doing you have packed on muscle. One summer I was 143, what I will call soft weight after a long winter. I started helping my welder hubby and doing some heavy lifts, mowed grass, rode the horse daily, cleaned her stall. By late Fall I stepped on the scales, something I rarely do, and was horrified that I weighed 161 lbs. Since we were going out to a formal dinner I put on a dress and it was huge. It fit nicely when I bo't it 6 mos before. I hadn't even noticed my jeans were hanging on me. I happened to look in a mirror as I lifted a glass of water and was shocked at the size of my biceps. I stepped back to have a better look and was pleased that I was lean and fit, so the number on the scales has nothing to do with how fit you are.
