This Instead of That

So this morning I was feeling a little under the weather so I decided to skip the gym today and that I would go on Thursday to make up for it. However, since I was running late for work and had missed lunch, I stopped at Taco Bell and got something to eat. I ordered 3 soft shell tacos with just meat and cheese and a diet pepsi. I don't think that it was all that bad of a lunch and its not something that I get on a regular basis. So anyway, once I got home I was feeling better and since I was feeling a little guilty about the Taco Bell run, I decided to do a workout video. I did The Biggest Loser Cardio Max and that was HARD!! I was sweating so bad. I checked my heart rate while I was doing it and that is the highest it has ever been. My heart was at 172 bpm. I burned about 400 cals. if my watch is right. I might have to work that in more often, maybe one or 2 days a week. Maybe that will help me lose the weight even faster. For those who don't have a gym membership this video is a 6 week workout boot camp. It is intense!! So after my workout I made chicken for dinner and then we took Molly for a walk. We did the 45 minute walk, which I was about half way through when I decided that I should have done the shorter walk. My legs felt like rubber after doing the cardio workout. So between the walk and the workout I burned about 700 cals. I looked up the reviews on my watch and they said that it was pretty accurate, so I guess that it means that I am burning about what the watch says I am! Yay, I would hate to find out my watch said that I was burning 2000 a day and I was actually only burning about 1200 or something like that. But anyway, I feel better about my day after having done that workout. The only problem I had with doing it was my feet. My arches started to hurt so bad that I would have to stop during the workout and give my  feet a break. I have no idea why they would hurt that bad. I have done that workout in the past and have never had that problem before. Any suggestions?
