Well first thing first, keep in mind that it takes 30 days for something to become a habit.... so commit to a month of exercising and see how it goes, maybe get a friend to help out during those thirty days.
AND - if that does not do the job, then cut out a PIC of a sexy female body and then paste your head shot over her head - NOW place it on the FRIG!!!
