Another big man here. I have done this program several time and love the combination of run/walk. When I started this time my weight was 323 but am able to run. My 2 cents is to take your time do not be afraid to spread thing out over a week and a half or even two weeks for every week in the program. You know your body but you need to push yourself. The reason I got to my weight was excuses so I tried not to give myself that may and trust in the program. There were several weeks that I repeated especially when you go from jogging 3 minutes to 10 minutes in only a few weeks. good luck
