I think the conclusion I'm coming to is that it's easier to exercise every day--and just do it--than to exercise 3 or 4 days a week. Every time I miss a day it's harder to exercise the next day. It's harder to find the time anyways with 3 kids! After I had Autumn, I worked out 2-3 times a day until I lost my pregnancy weight. After Sami, I worked out 1-2 times a day. And this time, I walk in place when I'm standing in line somewhere just to try and get some kind of workout in!
