wow lost pounds in a month

Yesterday I had bought a good scale. I had the small white scale that was only $6. It really wasn't working that much. Of all the workouts I did in the gym on the treadmill and the elliptical I felt great. But since I have to stay home now since my car isnt working I finalll went on the scale this morning and it said I weight 137.2 pounds. I lost 7 pounds in one month. I am so happy. I now have to change my weigh in here since I haven't been on in a while. I had gained weight since then. I have to keep on going.
