I'm a big girl. I never did exercise and have tried all diets going. I started weight watchers and in 3 weeks have lost 8lbs. I joined a gym, have been going 3 times a week for 40 mins each time. Which is good as used to do NO exercise! Have been counting my points religiously. My gym is ok but my personal trainer is a bit wishy washy. Went for my weigh in today and he tells me I have put on 2.5lbs!! I came home and cried, but when I checked my WW app I had stayed the same! I had updated it from the last time I got weighed at the gym. So do I go by that and my "own eyes" when I checked the scales I had stayed the same! I came home and was so upset. 2 and a half pound is a hell of a lot!!
