I am 40. Totally unfit. Toyed with exercise for 3 weeks here, 4 weeks there occasionally in the past but nothing long enough to make any difference. I suppose because I have never been fit I find it hard to visualise myself as being able to be fit and can't imagine what it would feel like. Exercise and sport has never been a constant part of my life. So all you ex unfit MN-ers - come and motivate me and tell me how you have changed your life, fitness level, body,weight, health etc because if I am worried that if I don't change now I never will!
