I've just finished the 12-week course and I'm starting again. I have lost a bit of weight. I had just hit 11 stone for the first time ever and felt so ungainly. I am down to 10 stone 3 pounds today but I still show as over-weight. I'm giving it another go and aiming to get to 9 stone 11 pounds this time. Although really I think a bigger target would be better (losing one stone 11 pounds was suggested by NHS site).
