When I was a SAHM, I went when the kids were in preschool/school or I used the gym child care.
Now I am WOTH full time and I have a free gym in my building at work, or else I have no idea when I would exercise. So I exercise on my lunch 4-5 days a week. If I lived closer to work, I would try to wake up early and do it before I left for work. But right now doing it at lunch works best for me. It also makes me pack my lunch vs eating out for lunch which also helps.
Exercise videos are good too and inexpensive vs the cost of a gym. And there are so many resources on the web now for training ideas, routines, etc.
