Not that exercise isn't important - IT IS! B-u-t...weight loss is mostly nutrition. I say this because I have seen many (myself included) that have this idea that if I can't exercise, I might as well not bother to stay on plan. It's easy to use "no time" as an excuse not to lose weight. If you don't have an hour to exercise in the morning, you could use 15 minutes to pack a healthy lunch/snacks for work and put something healthy in the crock pot dinner.
With that said, you don't need an uninterrupted hour of time in order to get benefits from exercise. Maybe you can find 1/2 hour 6 or 7 times per week (maybe some days two in the same day and not all on others depending on your schedule). In half an hour, you can try the Couch to 5k program or do some strength training or do a fitness video or take a walk or play a dance video game. OR - look at your schedule and decide that your time to be active isn't the "last priority" or "the thing that needs to be fit in if nothing else is going on." I think we all have this idea that we list all of the things we have to do and if and only if there is a free moment, then maybe we'll use it to exercise. Think about your priorities. Maybe once a week someone else can take the kids to practice or maybe you can change your work schedule to give yourself an hour and a half lunch so you can workout, etc. Make yourself more of a priority. We're worth it and it's good for our families when we are happier, too!
