a good motivation may be 'If I don't take more exercise I'll probably die very early' - shake a leg and stop looking for massive changes (if you have all sorts of exercise equipment and don't use them then they aren't right for you.) What are your interests? Join one of the many clubs that renovate gardens, build stone walls whatever, volunteer to work at a local animal shelter, push a disabled person out in their wheelchair once a week, join a bowling, table tennis, swimming club, anything that gets you moving -I have a lot to do with horses and believe me I take plenty of exercise but I'm interest in that. It will be too late to look for motivation when you are bedridden with a stroke or something - look out for boot in post and apply vigorously to backside.
