One of the more effective techniques I have started occurs at my job. We have such a high ratio of obese employees there that they have installed an escalator to get from the parking area to the production floor, you know, so we don't have daily visits from the ambulance for heart attacks. Well I have taken the fitness approach to this aspect of my job and I now walk up the escalator. It is pretty rough, but I am usually able to make it to my desk after a quick italian shower in the restroom sink to stop the profuse sweating. Maybe some day I will be fit enough to take the manual stairs next to the escalator.
My routine is still in development, and I am pretty sure I have been losing weight (I can't weigh myself because I am unable to afford the required agricultural-grade bovine scale), and my girlfriend said I looked thinner, but that might just have been because I recently fished a sweater's worth of bellybutton lint last week. So wish me luck. I am going to need it.
