I am a few years off fifty and am starting to really feel the effects of not looking after my body. I have never liked sport and have never managed to stick to exercise for more than a few weeks. Is there any hope? Has anyone managed to go from a lifetime of no exercise to actually enjoying keeping fit and where do you start? I do actually walk a lot but I have joint problems and that is starting to be a problem. I think if pain stops me walking I will lose all mobility pretty quickly as I am so stiff. Help!
