maybe instead of spending money on a new treadmill, join a gym with daycare. I have 3 kids, 10,7 and 5. There is nothing better than being able to work out without distractions!! good luck
I live in the small great white north, there are no gyms here! We have a city gym that we can access but no childcare, if it fit my schedule I could get dh or my mom to watch the kids. It's a good idea, I'll have to look into the hours for that gym and fit that in my schedule as well.
