It is hard to get fit when you have young children, but it can be done. I just wish I had included the kids a little more when they were very young, like by getting a bike trailer. Instead I woke up at 4:30 AM, so I could go to the gym at 5. Once they got to be 5 or 6, I did take them hiking, x country skiing, etc. But, it was more of a special thing. I think it's good to make it part of your daily life.
