Chubby Momma Needs to RUN!

I've gained 40 lbs. in the last 3 years! I eat fairly healthy but I can't exercise with two monkeys. So I would LOVE to have a double jogging stroller to lose these 40 lbs & be able to take the kids with me. I don't believe in taking pills (although that would probably be easier). I believe in no pain no gain (or lose in this case). I'm a stay at home to 4 kids! 2 are ours and my 16 yr. old sister in law and 17 yr old brother in law. We took them in because they were living in a dangerous situation. I love them like my own but due to being a family of 6, we simply can't afford this luxury.
