Weight Loss and Exercise 2

I am on track towards my goal. I have increased my walking at work. I am doing so much now that I am getting blisters and my co-workers are asking me to sit down instead of the inmates. I did 20 min. of step aerobics last night on the Wii while watching TV. Gonna shoot for 30 min. tonight. Diet is so-so. Not eating much but that has nothing to do with dieting. Wii said I was 276 lbs last night and the regular scale said 280 this morning so not sure which is accurate. Trying to stay optimistic about this whole thing.
